A 100 kg cart accelerates from 0 to 20 m/s in 5 seconds. What is the acceleration?

the mass does not matter.

a = (20m/s)/(5s) = (20/5) m/s^2

To find the acceleration, we can use the formula:

acceleration = change in velocity / time

Given that the initial velocity (u) is 0 m/s, the final velocity (v) is 20 m/s, and the time (t) is 5 seconds, we can substitute these values into the formula:

acceleration = (v - u) / t

acceleration = (20 - 0) / 5

acceleration = 20 / 5

acceleration = 4 m/s^2

Therefore, the acceleration of the cart is 4 m/s^2.
