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

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

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
