Question

A force of 50 N acts on a stationary body of mass 10 kg for 2s. The acceleration produced in the body and velocity attained by it is
(a) 10 m/s
(b) 20 m/s
(c) 30 m/s
(d) 40 m/s​

Answer 1

Answer:

F = ma

a = F / m

a = 50/ 10

a = 5 m/s²

since v = at

therefore, v = 5 X 2

v = 10 m/s

Answer 2

Answer:

N=M×A

A=V-U/T

N=50

M=10

U=0

T=2

find V

N=M×(V-U/T)

50=10×a

a=5

V-U/T=5

x-0/2=5

x-0=10

x=10

velocity =10
