A physics student stands on a cliff overlooking a lake and decides to throw a golf ball to her friends in the water below. She throws the golf ball with a velocity of 21.5 m/s at an angle of 32.5° above the horizontal. When the golf ball leaves her hand, it is 17.5 m above the water. How far does the golf ball travel horizontally before it hits the water? Neglect any effects of air resistance when calculating the answer....
a physics student on planet Exidor throws a ball, and it follows the parabolic trajectory shown in the figure. The balls position is showboat 1s intervals until t=3. At t=1s the balls velocity is v ->=(2.0i^+2.0j^)m/s. Determine the ball's velocity at t=0,2,3s. What is the value of g on planet Exidor? What is the ball's launch angle?
