Question

A force of 1n act on a body of mass 5kg the body covers 100 cm in 2 seconds moving along a straight line.the initial velocity is

Answer 1

Answer:

Explanation: force= Mass x acceleration

1= 5 x a

a= 1/5

We know that,

s=ut+1/2at2

1=2u+2/5

U=6/5 m/s= 1.2 m/s

Answer 2

Answer:

Explanation:

2u =1-2÷5

2u=5-2÷5

2u=3÷5

U=3÷10

U=0.3 m=30cm
