# Question Solved1 Answer3. Often times in football a punter may not need to kick the ball very far, but rather kick the ball high so that the other players have a lot of time to run down and make a tackle. If a punter punts a ball from 1.5 m high with an initial velocity of 25 m/s at an angle of 72º to the horizontal, what are the maximum height and time of flight for the ball? Assume the ball lands on the ground. [6 A]

x-componant of initial speed u_(x)=u cos thetay-component of initial speed, u_(y)=u sin thetaSo, meximum height from the ground is,H=1.5 m+P_(y)Here, s_(y)=(u_(y)^(2))/(2g)=(u^(2)sin^(2)theta)/(2g)=28.84mSo, +1=1.5 m+28.84m=38F^(2)=30.34m=>+1=30.34mquad rarr" meximum height. "If T is the time of flight, then, at time T, the verticel (along y axip) distance travelled by the ball is =h_(y)=-1.5m[negative ... See the full answer
