Question

Part F and B are wrong

A ball is kicked from a location m (on the ground) with initial velocity m/s. (a) What is the velocity of the ball 0.5 seconds after being kicked? velocity at time 0.5 s = (- 12,5.095,- 7) m/s (b) What is the location of the ball 0.5 seconds after being kicked? location at time 0.5 s = (3.5,1.22625,- 5.5) m (c) How much time does it take for the ball to reach its maximum height, where vy = 0 momentarily? time to reach maximum height = 1.0204 s (d) What is the maximum height? maximum height = 5.102 m (e) At what time does the ball hit the ground? time when it hits the ground = 2.039 s (f) What is the location of the ball when it hits the ground? location when it hits = (- 5,0,- 25.273) m

Explanation / Answer

b)x=7-12*0.5=1m

y=10*0.5-4.9*0.5^2=3.78m

z=-11-7*0.5=-14.5m

Location is<1,3.78,-14.5>

f)time of flight=2*time for max height=2.041s

x=x0+vx*t=7-12*2.041=-17.5m

y=0 ( on the ground)

z=-11-7*2.041=-25.3m

Location is <-17.5,0,-25.3)
