Question

A force of five Newton acts on a stationary ball of mass 2 KG its speed after two second will be

Answer 1

Answer:

Velocity is 5m/s

Explanation:

Here F=5N

mass=M=2kg

From relation

F=ma

5=2a

a=2.5m/s²

And Acceleration is given by

a=$\frac{v}{t}$

v=at

v=2.5*2

v=5m/s

Answer 2

Answer:

5m/s

Explanation:

a=F/m=5/2 m/S2

V=u+at=0+5/2×2=5 m/s
