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 small ball (ball 1) is released from rest; i.e. dropped, at the origin (0,0) and falls freely. At the same time another ball (ball 2) leaves the same position with an initial horizontal velocity of 2.70 m/s. Calculate the time it takes ball 1 to fall 3.50 m. What is the time it takes ball 2 to fall 3.50 m? Calculate the horizontal distance ball 2 will move during this time. Calculate the vertical component of the velocity of...
