Question

) An object of mass 5 kg is moving with a velocity of 10 ms!. A force is applied so that
in 20 s, it attains a velocity of 25 msl. What is the force applied on the object?
​

Answer 1

Answer:

formula used-

F=M x a

a=v-u/t

__________________________

given-

M= 5kg

u=10m/sec

v=25m/sec

time= 20 sec

______________________

to find force we need to find acceleration..

a=v-u/t

a=25-10/20

a= 15/20=3/4 m/sec^2

F=M x a

F= 5 x 3/4

F= 15/4= 3.75 N
