A particle of mass `0.2 kg` is moving in one dimension under a force that delivers constant power `0.5 W` to the particle.If the initial speed =0 then the final speed (in `ms^(-1)`) after `5s` is.

A particle of mass 0.2 kg is moving in one dimension under a force that delivers constant power 0.5 W to the particle. If the initial speed (in ms^(-1) ) after 5s is.

A particle of mass 0.2 kg is moving is one dimension under a force that delever is a constant preses 0.5 W in the particle . If the detail speed (n ms^(-1)) of the particle is zero , the speed (mms^(-1)) after 5 xx is

A particie of mass 10 kg is driven by a machine that delivers a constant power of 20 watts. If particle starts from rest and moves along a straight line, then force (in Newton) on particle at time t(t> 0) is

A body of mass m = 1 kg is moving in a medium and experiences a frictional force F = -kv, where v is the speed of the body. The initial speed is v_(0) = 10 ms^(-1) and after 10 s, its energy becomes half of the initial energy. Then, the value of k is

A particle of mass 2 kg is moving in circular path with constant speed 20 m/s. The magnitude of change in velocity when particle travels from A to P will be

A particle of mass 10 kg moving eastwards with a speed 5 ms^(-1) collides with another particle of the same mass moving north-wards with the same speed 5 ms^(-1) .The two particles coalesce on collision.The new particle of mass 20 kg will move in the north-east direction with velocity

A body of mass 10 kg is being acted upon by a force 3t^2 and an opposing constant force of 32 N. The initial speed is 10 ms^-1. The velocity of body after 5 s is
