Question

A coin is rolled in a straight line along a balcony edge at a steady speed of 0.46 m/s.
a) Calculate how far the coin rolls in 2.4 s.
b) Another coin is dropped from the balcony. It accelerates from rest and hits the ground after
8.0 seconds at a speed of 78.4 m/s. Calculate the acceleration of the coin during its fall

Answer 1

answer:

Use this equation (v=Δx/t); plug in velocity (0.500 m/s) and the time (2.4 s), then solve for displacement… (Δx=1.2 m)
