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. 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.
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.
You throw a ball toward a wall at speed 25.0 m/s and at angleθ = 40.0 degrees above the horizontal. (Fig. 4-38) The wallis distance d = 22.0 m from the release point of the ball.(a) How far above the release point does the ball hit the wall?What are the (b) horizontal and (c) vertical components of itsvelocity as it hits the wall? (d) When it hits, has it passed the highest point on its trajectory?
A football is kicked into the air at an angle of 45 degrees with the horizontal. At the very top of the ball's path, its acceleration is ___________. (Neglect the effects of air resistance) A. maximum B. minimum C. constant D. zero
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.)
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 22.4 m/s at an angle of 48.0° to the horizontal. By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short.)
A projectile is fired horizontally at V0 velocity from the top of an h-high cliff. Immediately after, it enters a fixed tube of length x. There is friction between the bullet and the tube, and the friction causes the bullet to slow down with constant ax acceleration. After the bullet leaves the tube, it fires a normal oblique shot towards the ground. Calculate the horizontal path of the bullet. (g = 9.8 m / s)
An alpine rescue team is using a slingshot to send an emergency medical packet to climbers stranded on a ledge, as shown in Fig. 4-34 (height = 258 m, horizontal distance = 406 m, landing angle = 67° below the horizontal). (Hint: It might be helpful to run the problem in reverse, with the top of the mountain representing the launch point.) What should be the launch speed from the slingshot? ______ m/s What is the launch angle? ______° What is the time of flight? ______ s
A placekicker 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 23.8 m/s at an angle of 52.0° to the horizontal. By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short.)

A rocket is launched at an angle of 59.0° above the horizontal with an initial speed of 101 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 28.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. (a) Find the maximum altitude reached by the rocket.-- m (b) Find its total time of flight. -- s (c) Find its horizontal range. -- m
Which of the following will reach the maximum height? a. A golf ball is hit at an angle of 45° above horizontal with a speed of 50 m/s. b. A golf ball is hit at an angle of 50° above horizontal with a speed of 45 m/s.
