Question

An object weighing 600g is moved from rest such that it attains a velocity of 60 m/sec when a force of 24 N is applied on it. How much time would the object need to attain this velocity?


Please answer immediately

Answer 1

Explanation:

Correct option is

B

4 N

From above figure

A→B

u = 4m/s v=0 t=2sec a=?

v=u+at

0=4+a(2)

a=−2m/s

2

so,

force = ma

=2×2=4N

Hence (B) is the correct answer
