A man throws a ball of mass \(0.4\ kg\) vertically upwards with a velocity of \(10\ m/s\). What will be its initial momentum? What would be its momentum at the highest point of its reach?
Answer
Given that,
Mass of ball \(m=0.4\ kg\).
Initial velcotiy of ball \(u =10\ m/s\).
Initial momentum of the ball will be given as,
\(P_i=mu=0.4\times 10=4\ kg\ m/s\).
At the highest point, velocity of ball is zero.
So momentum of the ball \(P_f=0.4\times 0=0\).
Mass of ball \(m=0.4\ kg\).
Initial velcotiy of ball \(u =10\ m/s\).
Initial momentum of the ball will be given as,
\(P_i=mu=0.4\times 10=4\ kg\ m/s\).
At the highest point, velocity of ball is zero.
So momentum of the ball \(P_f=0.4\times 0=0\).
