Concept explainers

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.

Question

Using d=1/2at^2

calculate the average acceleration for each object, along with a percent error from the accepted value of 9.8m/s.

drop height=10feet=3.048m

drop times of a cork:

1.1.03s

2.0.84s

3.0.64s

average drop time=0.837

Expert Solution
