Questions
A player kicks a foot ball obliquely at a speed of 20 ms-1 so that its range is maximum. Another player at a distance of 24m away in the direction of kick starts running at that instant to catch the ball. Before the ball hits the ground to catch it, the speed with which the second player has to run is (g = 10 ms-2)
detailed solution
Correct option is B
Rmax=u2g=20×2010=40m T=2usinθs=22s x=24mR−x=V×T16=V×22⇒V=42ms−1Similar Questions
