Question

A cart moves along a track at a velocity of 3.5 cm/s. When a force is applied to the cart, its velocity increases to
8.2 cm/s. If it takes the cart 1.5 seconds to reach 8.2 cm/s, what is the acceleration of the cart? Round your answer to the nearest tenth.

cm/s2

Answer 1

a = (8.2 − 3.5) / 1.5 = 4.7 / 1.5 = 3.133... ≈ 3.1 cm/s²
