1. A baseball is thrown upward at an angle of 20.0° with the horizontal from the top of a building 14.0 m high. The ball leaves the thrower's hand 1.80 m above the rooftop with a velocity of 30.0 m/s. Find a) the maximum height (measured from the ground) reached by the ball. b) the time of flight c) the range d) the velocity (magnitude and direction with respect to the horizontal axis) just before it strikes the ground

A basketball player is running at 5.00 m/s directly toward the basket when he jumps into the air to dunk the ball. He maintains his horizontal velocity. (a) What vertical velocity does he need to rise 0.750 m above the floor? (b) How far from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket?
A rocket is launched at an angle of 58.0° above the horizontal with an initial speed of 104 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. What is the total time of flight? What is the horizontal range?
In the Olympic shotput event, an athlete throws the shot with an initial speed of 11.0 m/sm/s at a 46.0 ∘∘ angle from the horizontal. The shot leaves her hand at a height of 1.80 mm above the ground. How far does the shot travel? Express your answer with the appropriate units.
In the Superbowl, a quarterback throws a football while standing at the very center of the field on the 50 yard line. The ball leaves his hand at a height of 5 ft and has initial velocity of ~v(0) =< 40, 35, 32 > ft/sec. Assume an acceleration of 32 ft/sec2 due to gravity, i.e., ~a(t) =< 0, 0, −32 >, and that the vector ~i points down fieldtoward the endzone and that the vector ~j points to the sideline. The field is 150 ft in width and 300 ft in length.(a) Determine the position function that gives the position of the ball t seconds after it isthrown. (b) The ball is caught by a player 5 ft above the ground. Is the player in bounds or out ofbounds when he receives the ball? (Assume the player is standing vertically with bothtoes on the ground at the time of reception.)
