Jamal is skating on a sidewalk. his initial velocity is 0.0 m/s; 35 seconds later his velocity is 5.0 m/s. what is his acceleration? -0.14 m/s/s -7 m/s 0.14 m/s/s 7 m/s

or

Explanation:

Acceleration is the rate at which the velocity of a body increases per unit time. Its S.I unit is meters per second per second. Mathematically it is given as follows;

where is the velocity, the initial velocity and t is the time taken.

Given;

We substitute all into equation (1) to calculate a as follows;
