Question

A ball released from rest at time $t=0$ hits the ground. It rebounds in elastically with a velocity $5m{s}^{-1}$ and reaches the top at $t=1.5s$, what is the net displacement of the ball from its initial position after $1.5s$? $(g=10m{s}^{-2})$

• A. $1.25m$
• B. $3.75m$
• C. $5.00m$
• D. $6.25m$

Answer 1

The correct option is C $5.00m$

$V=u-gt;O=5-10t;5=10t$
