The cart moves from rest with an acceleration of 0.2 m / s ^ 2. What speed will it acquire in 10 s from the start of movement?

We calculate the speed that the cart will acquire by the formula:

V = V0 + a * t, where according to the condition V0 = 0 m / s (the cart started moving from the rest state), a = 0.2 m / s ^ 2 (the cart acceleration), t = 10 s (the time of the cart movement) …

Let’s perform the calculation:

V = 0 + a * t = 0.2 * 10 = 2 m / s.

Answer: After 10 seconds from the start of movement, the trolley will acquire a speed of 2 m / s.
