Question

A particle starts from a point with a velocity of 6 metre per second hand moves with acceleration of 2 metre per second square so that after 6 seconds the particle will be at the starting point

Answer 1

Acceleration = Change in velocity ÷ time

In our case acceleration = 2

Our initial velocity = 6

We want to find the final velocity V

Our time is 6

6 = (V - 6) / 6

36 = V - 6

42 = V

V is thus 42 m/s
