13. A 0.04-kg ball is thrown from the top of a 30-m tall building (point A) at an unknown angle above the horizontal. As shown in the figure, the ball attains a maximum height of 10 m above the top of the building before striking the ground at point B. If air resistance is negligible, what is the value of the kinetic energy of the ball at B minus the kinetic energy of the ball at A (KB - KA)?...
9, Galileo throws a rock from the top of the Leaning Tower of Pisa at an upward angle of 69.00 with speed vo. The rock is in flight for 5.2 s and hits the ground 15 m from the base of the building. Ignore air resistance and ignore the fact that the two tilts a bit. a) What is the speed vo? Vo b) How high off the ground is the top of the tower? Height of tower c) What...
A ball is thrown horizontally from the top of a 60.0-m building and lands 110.0 m from the base of the building. Ignore air resistance. (a) How long is the ball in the air? (b) What must have been the initial horizontal component of the velocity? (c) What is the vertical component of the velocity just before the ball hits the ground? (d) What is the velocity (including both the horizontal and vertical components) of the ball just before it...
A ball is thrown horizontally from the top of a 63.0 -m building and lands 110.3 m from the base of the building. Ignore air resistance. What is the vertical component of the velocity (in m/s) just before the ball hits the ground? (Indicate the direction with the sign of your answer.)
A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the top of the building, with positive y upwards and positive x in the direction of the throw. Part (a) How long is the ball in the air in seconds? Part (b) what must have been the initial horizontal component of the velocity, in meters per second? Part(c)...
A ball is dropped from the top of a building 100 m high. (Ignore air resistance) a) How long does it take the ball to hit the ground? b) What is the speed of the ball when it hits the ground?
A ball is thrown horizontally from the top of a 69.0-m building and lands 105.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.) How long (in s) is the ball in the air? What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.) What is the vertical component of...
PROBLEM: A ball is thrown downward from the top of a building at an angle of 30.0° below the horizontal. The point of release is 49.0 m above the ground and the ball lands 67.7 m from the base of the building. (a) How long does it take for the ball to hit the ground? (b) Find the ball's initial speed. (c) the speed and angle of the velocity vector with respect to the horizontal at impact. Neglect air resistance.
A ball is thrown horizontally from the top of a 61.5-m building and lands 112.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.) (a) How long (in s) is the ball in the air? s (b) What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.) m/s (c) What...
A ball is thrown horizontally from the top of a 55.0-m building and lands 106.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.) How long (in s) is the ball in the air? s (b) What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.) m/s (c) What is...
