can someone help me???
Romeo is tossing pebbles at Juliet's window to wake her. Unfortunately, she is a sound sleeper and he finally throws too large a pebble too fast. If Romeo is standing at the edge of a rose garden h = 7.1 m below her window and d = 7.0 m from the base of the wall (Fig. 3-54), how fast are the pebbles going when they hit her window? Assume the pebbles strike the window horizontally.
A Hollywood daredevil plans to jump the canyon shown in Fig. 3.36 (d=56 m, h=14.5 m) on a motorcycle.
Assume he desires a 2.9 second flight time.
(a) What is the correct angle for his launch ramp?
° (above the horizontal)
(b) What is his correct launch speed?
m/s
(c) What is the correct angle for his landing ramp?
° (below the horizontal)
(d) What is his predicted landing speed? (Neglect air resistance.)
m/s
My question is below?
NICE ONE
