Question

A car accelerates from 20 m/S to 30 m/S in 10 s

Answer 1

Answer:

Acceleration of the car is 1 m/s²

Explanation:

Acceleration is defined as the rate of change of velocity. Here the velocity of the car changes from 20 m/s to 30 m/s. That is initial velocity, u = 20 m/s, and final velocity, v = 30 m/s. The time, 't' taken to change the velocity is given as 10 s. Acceleration, 'a' can be found using the equation:

a = (v-u) / t

a = (30 - 20) / 10

∴ a = 1 m/s²
