1 (a) A ball is launched from the ground toward a tall wall of a building at initial speed v0 = 21 m/s at an angle of 39 degrees relative to the horizontal. The wall is at a distance of 29 m from the launch point. What is the magnitude of the ball's velocity vector as it hits the wall?

Your answer should be in m/s, but enter only the numerical part in the answer box.

(b) A ball is launched from the ground toward a tall wall of a building at initial speed v0 = 27 m/s at an angle of 41 degrees relative to the horizontal. The wall is at a distance of 39 m from the launch point. What angle does the ball's velocity vector make with respect to horizontal as it hits the wall?  [Note: a negative answer means the ball is moving on a downward angle. Be sure to enter the correct sign!]

Your answer should be in degrees, but enter only the numerical part in the answer box.

Expert Solution

In order to calculate the magnitude of final velocity of the ball, we have to calculate the x and y component of initial velocity and then we can take the magnitude of velocity.

A student launches an elastic ball from the ground level directly toward a tall vertical wall. After the first launch, the ball bounces off the wall and then hits the ground. The student notices that the launch point is equidistant from the landing point and from the wall. The student then moves the launching point 20 m in the direction perpendicular to the wall and launches the ball again. After the ball bounces off the wall and lands, the student...

A 700 gram ball is thrown from the top of a 25 meter tall building. The ball is thrown with an initial speed of 10 m/s at an angle 30 degrees above the horizontal. For our conservation of energy calculations, we will choose the Ball + Earth as our system and use the ground as h = 0. The kinetic energy of the ball when it is thrown =   J. When the ball reaches its highest point the kinetic energy is...

A boy standing on the ground close to a building throws a ball vertically upward. From his measurements of the maximum height, y-max, to which the ball rises and the time required to reach this height, the boy calculates that the average velocity of the ball on its way up is 20 m/s. Five seconds after leaving the boys hand, the ball is caught by a girl who has stretched her arm out of a window some distance above the...
