A student determine to test the law of gravity for himself walks off a skyscraper 300m high, stopwatch in hand and starts his free fall (zero initial velocity). Five seconds later, Superman arrives at the scene and dives off the roof to save the student. What must Superman’s initial velocity be in order that he catch the student just before the ground is reach? (Assume that Superman’s acceleration is that of any freely falling body).

A physicist is studying the position of a baseball being thrown up in the air. He notices that the baseball goes up in the air and then comes back down. Which equation could model how high the baseball is off the ground over time?
Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.27 m, and observe that it hits the floor 0.204 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 81.8 m/s^2 81.8 m/s^2 109.1 m/s^2 54.5 m/s^2
A circus performer throws an apple toward a hoop held by a performer on a platform (see figure below). The thrower aims for the hoop and throws with a speed of 20 m/s. At the exact moment the thrower releases the apple, the other performer drops the hoop. The hoop falls straight down. (Assume d = 29 m and h = 48 m. Neglect the height at which the apple is thrown.) (a) At what height above the ground does the apple go through the hoop?
I was standing on the side of a 10-m foot bridge, holding a ball while watching a car approaching the bridge at uniform speed. When the car was 15 meters away from where I was standing, the ball that I was holding slipped in my hand and the car arrived at the bridge when the ball hit the ground. What was the speed of the train? ( Assume that the final velocity of the ball is NOT zero)
The Denver Nuggets Super mascot, Rocky, can fire T-shirts out of a potato cannon at a rate of 65 feet per second. The cannon propels the t shirts from an initial height of 8 feet above the ground. Is it possible for Rocky to fire t shirts to the upper deck of Ball Arena which itself is 70 feet above the ground?
The Hulk, on the 75th story of Stark Tower (225 m off the ground), sees Tony drop his penny. He catches the penny and throws it back to Tony. What is the minimum speed necessary for Hulk's throw in order for the penny to reach Tony? (Note: nobody bothers trying to get Mjolnir back to Thor. He's on his own.)
In 1989, Michel Menin of France walked on a tightrope suspended under a balloon nearly at an altitude of 3150 m above the ground. Suppose a coin falls from Menin’s pocket during his walk. How high above the ground is the coin when its speed is 60.0 m/s?
You're an investigator for the National Transportation Safety Board, examining a subway accident in which a train going at 90 km/hkm/h collided with a slower train traveling in the same direction at 24 km/hkm/h . Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 2.1 m/s2m/s2 when it was 52 mm from the slower train, while the slower train continued at constant speed. What do you report ?
A falling object experiment is performed to determine the acceleration due to gravity on an unknown planet (not the Earth) from photographic data of the falling object.At time = 0 seconds, the object's displacement is 0 m.At time = 0.4 seconds, the object's displacement is 1.9 m.From the above information, calculate the value of the acceleration due to gravity on the unknown planet.

Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.10 m, and observe that it hits the floor 0.393 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? Question 3 options: 13.6 m/s^2 20.4 m/s^2 46.2 m/s^2 27.2 m/s^2
Kendra is having her breakfast on a balcony 20m high when she accidentally knocks down a flower pot. A man, 10m away, is innocently walking along the street at a constant velocity of 4 m/s when the pot fell. Will the innocent man be hit by the pot, or will he miraculously be able to avoid the impending accident? The man is 1.7m tall. EXPLAIN AND PROVE YOUR ANSWER.
