Question 7 :
Two skaters P and Q are skating towards each other. Skater P throws a ball towards Q every $5$s such that it always leaves her hand with speed $2$ $ms^{-1}$ with respect to the ground. Consider two cases:<br>(i) P runs with speed $1$ $ms^{-1}$ towards Q while Q remains stationary.<br>(ii) Q runs with speed $1$ $ms^{-1}$ towards P while P remains stationary.<br>Note that irrespective of speed of P, ball always leaves P's hand with speed $2$ $ms^{-1}$ with respect to the ground. Ignore gravity. Balls will be received by Q.<br>

Question 8 :
