A person kicks a ball, giving it an initial velocity of
20.0 m/s up a wooden ramp. When the ball reaches the top, it
becomes airborne. The ramp makes an angle of 22.0º to the ground,
and the ball travels a distance of 5.00 m on the ramp. What is the
maximum height the ball reaches, above the point where it was
kicked, if (a) the ramp is frictionless and (b) there is a
coefficient of friction of 0.150 between the ramp and the ball?
Assume the ball slides, rather than rolls, up the
ramp.
Answer is: a) 4.47 m; (b) 4.37 m

One side of the roof of a building slopes up at 43.0°. A roofer kicks a round, flat rock that has been thrown onto the roof by a neighborhood child. The rock slides straight up the incline with an initial speed of 15.0 m/s. The coefficient of kinetic friction between the rock and the roof is 0.405. The rock slides 10.0 m up the roof to its peak. It crosses the ridge and goes into free fall, following a parabolic...
A soccer ball is kicked with an initial horizontal velocity of 20 m/s and an initial vertical velocity of 16 m/s
A soccer ball is kicked with an initial horizontal velocity of 20 m/s and an initial vertical velocity of 16 m/s. I've calculated: Initial Speed: 25.61 m/s Angle: 38.66 degrees Maximum Height it reaches: 13.06 m Distance kicked: 65.29m NOW I NEED: What is the speed of the ball 0.7 seconds after it was kicked? How high above the ground is the ball 0.7 seconds after it is kicked? help? please.
