Students have asked these similar questions

A diver jumps off a diving board horizontally with an initial velocity of 5m/s. He lands in the water 4m to the right of the base of the diving board. a) How high above the ground is the diving board? b) What speed will the driver have as he hits the water?

Your little sister is running to the park in your neighborhood at a speed of 3.90 m/s when you suddenly realize she left her favorite playground ball behind. You throw her ball horizontally out the window of your apartment which is at a height of 45.0 m above the street and directly above the sidewalk. You throw the ball 8.00 seconds after she has passed below your window and she catches the ball! a) Ignoring air resistance, what is the initial speed that you must throw her ball so she can catch it just before it reaches the ground? b) What is the angular frequency of the pendulum?
