Question

the momentum of a body changes from 6 kg m/s to 10 kg m/s in 8 seconds
it s the force applied on a body is​

Answer 1

Answer:

Step-by-step explanation:

As per second law of motion by sir issac newton

Rate of change of momentum is force

Hence force=10-6/8=4/8=0.5Newton

Answer 2

According to Newton's 2nd law :  the net force acting on the object is equal to the time rate of change of linear momentum

Now, change in momentum = 4kg.m/s

Time taken by the force to change the momentum =  8 seconds

Hence, Force applied during that interval= 4/8 Newtons OR 0.5 Newtons
