Question

an object of mass 5kg is moving with a velocity of 10ms-1 a force is applied so that in 15s it attains a velocity of 25ms-1 what is the force applied on the object ​

Answer 1

Answer:

f= m(v-u) /t

f= 5(25-10) /15

f=5N

Answer 2

Answer:

5N

Explanation:

force=mass(velocity-acceleration)/time

f=m(v-a)/t

f=5(10-25)/15

f=5(15)/15

f=5N
