A 0.1000-kg marble is fired by a boy from a slingshot at point A, at a height of 1.500 mfrom the ground. It hits a frictionless inclined concrete wall at point B, which is 30.0 maway from the boy. After hitting the wall, the marble rebounds with a velocity, VB.directed 140° from the horizontal as shown. The ball finally hits point C on thefrictionless floor. The velocity of firing, VA, is 20.0 m/s, directed 45.0° with thehorizontal.VA = 20 m/s14.14 m/s15.64 m/s06.67 m/s45°1.5 mC!7.47 m/s1.692 m/s2.02 m/s1.316 m/s30 mVB60°Which of the following gives the closest value of themagnitude of the velocity of the ball BEFORE it strikes theconcrete wall at point B?B= 140°Which of the following gives the closest value of themagnitude of the velocity of the ball AFTER it strikes theconcrete wall at point B?

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle of 37 degrees with respect to the horizontal and with an initial speed of 36 m/s. Air resistance is negligible in this situation. Call up the positive y direction, and toward the wall the positive x direction. Maximum height the projectile reaches: 23.948m Projectile speed at max height: 28.751m/s Earliest time when the height of the projectile is half of its maximum value: 0.648s The projectile is fired toward a wall that is a horizontal distance 106.6m from where the projectile was fired. What was the height of the projectile when it hit the wall?
