In a friendly game of handball, you hit the ball essentially at ground level and send it toward the wall with a speed of 16 m/s at an angle of 32° above the horizontal.
a) How long does it take for the ball to reach the wall if it is 5.2 m away?
(b) How high is the ball when it hits the wall?
Help me Please
a. X = hor. = 5.2 m,
d = 5.2 / cos32 = 6.13 m = distance ball must travel to reach wall.
d = V*t = 6.13 m,
16*t = 6.13,
t = 6.13 / 16 = 0.38 s.
b. h = ver. = 5.2 / sin32 = 9.8 m.
