A ball is thrown straight upward and returns to the throwers hand after 3.00 s in the air. A second ball thrown at an angle of 30.0 with the horizontal reaches the same maximum height as the first ball, (a) At what speed was the first ball thrown? (b) At what speed was the second ball thrown?
A playground is on the flat roof of a city school, 6.00 m above the street below (Fig. P3.21). The vertical wall of the building is h = 7.00 m high, forming a 1-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of = 53.0 above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (a) Find the speed at which the ball was launched. (b) Find the vertical distance by which the ball clears the wall. (c) Find the horizontal distance from the wall to the point on the roof where the ball lands. Figure P3.21
A playground is on the flat roof of a city school, 6.00 m above the street below (Fig. P4.25). The vertical wall of the building is h =7.00 in high, forming a 1-m-high railing around the playground.

You drive 7.50 km in a straight line in a direction 15 east of north. (a) Find the distance you would have to drive straight east and then straight north to arrive at the same point. (b) Show that you still arrive at the some point if the east and north legs are reversed in order. Assume the +x -axis is to the east.
A catapult launches a rocket at an angle of 53.0 above the horizontal with an initial speed of 100 m/s. The rocket engine immediately starts a burn, and for 3.00 s the rocket moves along its initial line of motion with an acceleration of 30.0 m/s2. Then its engine fails, and the rocket proceeds to move in free fall. Find (a) the maximum altitude reached by the rocket, (b) its total time of flight, and (c) its horizontal range.
A canon is located on the edge of a cliff overlooking the sea as shown below.The cannon is 45 m above sea level. The canon ball is fired at an angle of 60ofrom the horizontal with an initial speed of 50 m/s. Air resistance may beignored.i.) What will be its horizontal speed (in m/s)?[25%]ii.) What horizontal distance (in m) will it travel before it falls into the sea?[75%]

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.67 m/s at an angle of 81.0°above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?
A place-kicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 20.4 m/s at an angle of 50.0° to the horizontal. By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.)
