Question

A motorcycle is stopped at a traffic light. When the light turns green, the motorcycle accelerates to a speed of 95 km/h over a distance of 49 m.(a) How much time does it take for the tennis ball to reach its maximum height?(b) What is the maximum height above the ground that the tennis ball reaches?(c) When the tennis ball is at a height of 2.6 m above the ground, what is its speed?

Answer 1

Let's first name the variables that we're given and already know.

vi: initial velocity; vi = 0 km/h = 0 m/s

vf: final velocity; vf = 95 km/h = 26.3889 m/s

d: distance; d = 49 m
