Question

The magnitude of acceleration produced by a force of 5newton acting on an object of mass 10kg is

Answer 1

The ‘formula for acceleration’ is

Here, a is the acceleration, v is the final velocity, u is the initial velocity and t is time.

The given data’s are as such

v = -2 m/s

u = 10 m/s

t = 4 s

Hence, .

Thus, the acceleration is .

Acceleration is a ‘vector quantity’ defined as ‘the rate’ at which “an object changes its velocity”. An ‘object is accelerating’ if it is ‘changing its velocity’.
