The energy required to accelerate a body from 30ms^(-1) to 60 ms^(-1) is three times the energy required to accelerate it from 10 ms^(-1) to .v.. The value of .v. is

With the application of a force of 20N, the momentum of a body of mass 2kg changes from 16 kg ms^(-1) to 24 kg ms^(-1) . Then

The force required to tow a car at constant velocity is directly proportional to velocity. If it requires 160 W to two a car with a velocity of 4ms^(-1) , the power it required to move the car with a velocity of 9ms^(-1) is

A constant power of 7 W is supplied on a toy car of mass 15 kg. The distance travelled by the car when its velocity increases from 3ms^(-1) to 5 ms^(-1) is
