A pitcher throws a 120-g ball horizontally with velocity v = 35.0i m/s,
and it lands in the catcher's glove 0.525 s later. What is the momentum of the ball the instant before it lands in the glove? Ignore air resistance. (Express your answer in vector form.)

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
