Question

for part B, without useing heigh maximum formula, how can i do with other formula??? such as y=1/2(Vy+Voy)t

A tennis player hits a hall at ground level, giving ii an initial velocity of 24 m/s at 57 Degree above the horizontal, What are the horizontal and vertical components of the ball's initial velocity? I low high above the ground does the ball go? How Jung does it take the ball to reach its maximum height? What are the ball's velocity and acceleration at its highest point? l or how long a time is the ball in the air? When this ball lands on the court, how far is it from the place where it was hit?

Explanation / Answer

a) Vv=20.13M .. Vh=24 cos 57 =13.07m/s

b) (Vhsin27)^2/2g = 20.26m

c) v= u+gt ; 20.13/9.8 = 2.06s

d)Vh=0; A=-9.8

e) 2*2.06 = 4.12s

f) Vh*4.12 = 53.84m
