(a) At its maximum height, the vertical component of velocity is zero. Since there is no horizontal component, the magnitude of velocity (speed) and momentum are also zero.

(b) Half way up, the speed is 1/sqrt2 = 70.7% of the original value. (Conservation of energy should tell you why).

Compute the corresponding momentum,

M*V=(0.15)(0.707)*13 = ?
