Using F=m(v-u) /t

where f=ma
Ma = m(v-u)/t
a = (v-u) /t
a= (-0.4-0.6)/0.2
a= -1/0.2 = -5ms-² (it's decelerating)

Dave throws a 10 kg bowling ball straight up in the air. At the very tippy-top of its path, what is it's momentum?
svetoff [14.1K]

Answer:Zero

Explanation:

Given

mass of ball m=10\ kg

If the ball is thrown upward then at maximum point velocity of ball is zero because ball is no longer able to move upward

Momentum(P) of a particle is given by

P=mass\times velocity

P=10\times 0

P=0

Therefore at the highest point momentum is zero .
