What is the weight of a body of mass 20 kg at the equator ?

What is the weight of a body of mass 20kg at the equator ?(g=9.78 m/s^2)

The momentum of a body of masss of 5kg is 500kg ms^(-1) . Find the its K.E.

A force is applied on a body of mass 20 kg moving with a velocity of 40ms^(-1) . The body attains a velocity of 50ms^(-1) in 2 second. Calculate the work done by the body.

What is the de Broglie wavelength of a ball of mass 0.12 Kg moving with a speed of 20 " ms"^(-1) ? What can we infer from this result ?

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
