Question

A force of 25 newton is applied on an object of mass 10 kg moving
with a velocity of 5 ms. If the object gains a velocity of 10 ms.
calculate the time taken.​

Answer 1

Answer:

F=ma

a=F/m=25 N/10 kg =2.5 m/sec^2

Since a= change in velocity / change in time

change in time= (change in velocity)/a=(10 m/s- 5 m/s)/(2.5 m/sec^2)= 2 sec

Answer 2

Answer:

t=2s

Explanation:

F=MA

25= 10A

A=2.5

Total velocity= 10-5=5 Acceleration=velocity/ time

2.5=5/t

t=2s
