A child standing at the top edge of a 21.0-m high cliff kicks a soccer ball. The ball’s initial velocity is 13.1 m/s, in a direction 31.2° above the horizontal. Ignore drag for this problem. Provide all answers to 3 SF. (a) State your choices for the speed and direction of the initial velocity, and use them to calculate the horizontal and vertical components of the ball's initial velocity. (b) Calculate the vertical component of the ball's velocity just as...

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...
