Question

if a cart started rolling down a hill at 2 m/s, and 5 seconds later it was moving at 12 m/s, what was the carts accelaration

Answer 1

Answer:

2 m/s^2

Step-by-step explanation:

Acceleration is the rate at which the speed changes.

a = (new speed - old speed)(time)

a = (12 m/s - 2 m/s)/(5 s)

a = (10 m/s)/(5 s)

a = 2 m/s^2
