- A toy car starts at rest and accelerate up a 40" ramp with acceleration a=√(t^3). It then flies into the air, and lands back on the ground. If the height of the ramp is h=6 m, what is the horizontal distance ?To Merge into the highway you need to increase your speed from 50 km/h to 100 km/h. If your car can accelerate at 8.0 m/s², what should the minimum length of the ramp be? (report your answer in meters) Your Answer: AnswerA ski jumper starts from rest 54.1 m abovethe ground on a frictionless track and fliesoff the track at an angle of 43.8◦above thehorizontal and at a height of 10.8 m above thelevel ground. Neglect air resistance.The acceleration of gravity is 9.8 m/s2.What is his speed when he leaves the track?Answer in units of m/s. b) What is the maximum altitude he attainsafter leaving the track?Answer in units of m. c) Where does he land relative to the end of thetrack?Answer in units of m.
- The best rebounders in basketbal have a vertical leap of about 111.13 cm. What is their initial "launch" speed off the ground? Answer: Check1. Falls resulting in hip fractures are a major cause of injury and even death to the elderly. Typically, the hip's speed at impact is about 2.0m/s. If this can be reduced to 1.3m/s or less, the hip will usually not fracture. One way to do this is by wearing elastic hip pads. (a) If a typical pad is 5.0 cm thick and compresses by 2.0 cm during the impact of a fall, what constant acceleration (in m/s²) does the hip undergo to reduce its speed from 2.0 m s to 1.3m/s (b) The acceleration you found in part (a) may seem rather large, but to assess its effects on the hip fully, calculate how long it lasts. Note: convert cm to m first.A bottle dropped from a balloon reaches the ground in 50.0 s. What was the height, in meters, of the balloon above the ground, if it was ascending with a speed of 20.0 m/s when the bottle was dropped? [Neglect air resistance.
