A ball is thrown stright upwrd and rises to a maximium height of 19.8 m above its launch point.At what height above its launch point has the speed of the ball decreased to one- half of its initial value?
An object is thrown vertically and has an upward velocity of 18 m/s when it reaches one fourth of its maximum height above its launch point. What is the initial (launch) speed of the object?
A ball of mass 0.200 kg is thrown straight upward. It reaches a maximum height of 5.00 mm above the point where it left the thrower's hand. Air resistance acts on the ball as it rises. −9.80J 9.80J zero not enough information is given to calculate the answer Part A How much work was done on the ball by the force of gravity during the time from when it left the thrower's hand to when it reached its maximum height?...
A ball is thrown straight up with an initial speed of 14.3 m/s. At what height above its initial position will the ball have one-half its initial speed? height:
A ball is thrown straight up with an initial speed of 13.7 m/s. At what height above its initial position will the ball have one‑half its initial speed?
A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.6 meters above the ground. 2.8 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.7 m/s from a height of 28.2 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. ) What is the speed of the...

Ignore air resistance. a) What is the maximum height the ball will reach? b) What is the speed of the ball when it reaches 5.00 m?c) How long will the ball take to reach 5.00 m above its initial position on the way up? d) How long will the ball take to reach 5,00 m above its initial position on its way down?
A 0.36-kg ball is thrown vertically upward with an initial speed of 12.5 m/s. What is the potential energy of the ball when it has travelled two-thirds of the distance to its maximum height? (Use the launch point to be the zero reference point of measurements of the heights)
An object is thrown vertically and has an upward velocity of 25 m/s when it reaches one fourth of its maximum height above its launch point. What is the initial (launch) speed of the object?
A ball is thrown upward at a speed v0 at an angle of 53.0˚ above the horizontal. It reaches a maximum height of 8.1 m. How high would this ball go if it were thrown straight upward at speed v0?
