Question

a tennis ball is fired from a gun that us mounted on the floor. the tennis ball has an initial speed Vo= 25.0m/s and is launched at an angel if 0o=35degree above horizontal. You are standing 57meters Away from the gun.
A) at what time do you catch the tennis ball ( assume that t=0 when the ball is fired).
B) what is the height of the ball above ground when it reaches your racket?
C) what is the speed of the tennis ball when it reaches your racket?
A) at what time do you catch the tennis ball ( assume that t=0 when the ball is fired).
B) what is the height of the ball above ground when it reaches your racket?
C) what is the speed of the tennis ball when it reaches your racket?

Explanation / Answer

It reaches at time 57/(25cos35)=2.783 secs

Height= (25sin35)*2.783-5(2.783)^2=39.9-38.725=1.175 m

Speed= root(25cos35^2 + (25sin35-10*2.783)^2)=24.52
