Oscar throws a ball toward a wall with a speed of 25 m/s at an angle of 40° above ground. The wall is 22 m from the release point of the ball.  How far above the release point does the ball hit the wall?  What is the magnitude and direction of the ball’s velocity as it hits the wall? When it hits the wall, has it passed the highest point on its trajectory?

A projectile is fired with an initial speed of 32 m/s at an angle 65° above the horizontal. The object hits the ground 8.5 seconds later. Using 9.80 m/s2 for the local acceleration due to gravity, how much higher or lower (in m) is the launch point relative to the point where the projectile hits the ground?    To what maximum height (in m) above the launch point does the projectile rise?  What is the magnitude of the projectile's velocity when it hits the ground?        What is the angle (in deg) of the projectile's velocity below the horizontal when it hits the ground?

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 7.27 m/s at an angle of 83.0° above the table. With what speed (in m/s) does the pea strike the ceiling 2.10 m above the table?

3.19 Win the Prize. In a carnival booth, you can win a stuffed giraffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal distance of 2.1 m from this point (Fig. E3.19). If you toss the coin with a velocity of 6.4 m/s at an angle of 60 degrees above the horizontal, the coin will land in the dish. Ignore air resistance. (a) What is the height of the shelf above the point where the quarter leaves your hand? (b) What is the vertical component of the velocity of the quarter just before it lands in the dish? Figure E3.19

Emily throws a soccer ball out of her dorm window to Allison, who is waiting below to catch it. Emily throws the ball at an angle of 30° below horizontal with a speed of 12 m/s, and Allison catches it 2.5 s later. How far from the base of the dorm does Allison stand to catch the ball, in meters? Use g = 10.0 m/s2.

A cannon ball is fired at a wall that is 300 m away on level ground. The initial velocity of the cannon is 89 m/s, 40° above the horizontal. Don't assume the ball hits the wall at maximum height! What is the y-component of the ball's velocity when the ball hits the wall? h V; = 89 m/s 40° 300 m O 89.0 m/s O 9.81 m/s O 7.60 m/s O 18.2 m/s O 14.1 m/s O 2.99 m/s

Billy launches a tennis ball with a sling shot at an angle of 62 degrees above the horizontal at a speed of 45 meters per second . The tennis ball lands in a nearby tree. How far away is the tree?

A ball is fired at a speed of 8m/s at 20° above the horizontal from the top of a 5m high wall. How far from the base of the wall will the ball hit the ground?

Several people stand on a bridge over a river.  The bridge is not level, so the people are all different heights above the river.  Each person throws a stone to the river. a) The first person is 26.8 m above the river and throws her stone with a speed of 16.6 m/s at an angle of 6 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  How long does it take her stone to hit the water, in seconds? b) The second person is 19.0 m above the river and throws his stone with a speed of 17.1 m/s at an angle of -21.4 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  What is the range of his stone, in meters? c)The third person is 9.1 m above the river and throws their stone with a speed of 6.5 m/s at an angle of 9.3 degrees to the horizontal (positive degrees are above horizontal, negative degrees are below).  What is the speed of this stone (in m/s) just before it strikes the river?

A cannon is mounted on a tower above a wide, level field. The barrel of the cannon is 80 m above the ground below. A cannonball is fired horizontally with an initial speed of 800 m/s. Assuming air resistance can be neglected, approximately how long will the cannonball be in flight before it hits the ground? О 16 s 40 s 4 s 32 s 2 s About how far from the base of the tower will the cannonball land? 3000 m 800 m O 160 m 40 m 60000 m
