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 ball is launched from the ground at an angle of 65∘ above the horizontal with a velocity of 22m/s. The ball hits the ground some distance away at a given speed, and bounces back up. When it does so the amplitude of both the x and y components of its velocity are half what they were. This repeats with the ball losing half of it’s speed on each bounce. a) Sketch the problem. b) Write the equation of motion...

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...
