- A baseball with mass of 0.16 kg is batted into the air. Its initial speed is 35.0 m/s, directed at an angle 39 degrees above the horizontal. If the height of the ball when it was struck by the bat is 35 cm, how high off the ground (in m) is the ball when it reaches the highest point in its trajectory?A projectile is fired horizontally to the north at a velocity of 40 m/s.Let us consider the fall of a pole vaulter as a projectile once he releases the pole. The pole has a lake of 15 8 feet and once the athlete releases the pole he will find a mattress 2 feet high, 10 feet wide and 16 feet long, which protects him in the fall. If an athlete lets go of the pole when it was 13.7 ft above the ground with a speed of 15.7 ft/s at an angle of 73 degrees. Enter the horizontal distance that the athlete will travel with the indicated conditions, add the units in the result

Problem: A shot-putter throws an iron ball (7.26 kg) forward (due East). The initial velocity of the ball is 12.0 m/s, with respect to shot-putter’s hand, in a direction of 25.0° above the horizontal while the shot-putter also moves forward horizontally (due East) with a velocity of 3.50 m/s. At the moment of throwing the ball, his hand is 1.90 m above the ground. How long is the ball in the air after it leaves the shot-putter’s hand?
- A projectile is fired at ?0=394.0 m/s at an angle of ?=72.0∘, with respect to the horizontal. Assume that air friction will shorten the range by 33.1%. How far will the projectile travel in the horizontal direction, ??The average thrust created by the first stage engine of a model rocket is 50N. The rocket has an average weight of 10N with a burn time of 2 seconds. The rocket is initially fired vertically upward. When the rocket reaches maximum height, a second engine is fired creating a horizontal velocity (only) of 50m/s. Where does the rocket land relative to its launch point? Assume it was launched on a horizontal plain.a quarterback throws a ball with a velocity of 50ft/s at an angle 40 above the horizontal towards an open receiver who is 30yd away. The pass is released 5.0 ft above the ground. Assume the receiver is stationary and will catch the ball if it reaches him. Will it be a complete pass? If not will it fall short or ''fly'' to the receiver?
