An airplane flying directly eastward at a constant speed travels 300 km in 2.0 h. (a) What is the average velocity of the plane? (b) What is its instantaneous velocity?
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?
If an object is thrown straight up and air resistance is negligible, then its speed when it returns to the starting point is the same as when it was released. If air resistance were not negligible, how would its speed upon return compare with its initial speed? How would the maximum height to which it rises be affected?
A home run is hit in such a way that the baseball just clears a wall 21.0 m high, located 130 m from home plate. The ball is hit at an angle of 35.0 to the horizontal, and air resistance is negligible. Find (a) the initial speed of the ball, (b) the time it takes the ball to reach the wall, and (c) the velocity components and the speed of the ball when it reaches the wall. (Assume the ball is hit at a height of 1.00 m above the ground.)
An airplane flying horizontally with a speed of 500 km/h at a height of 800 m drops a crate of supplies (see the following figure). If the parachute fails to open, how far in front of the release point does the crate hit the ground?
A race car traveling northward on a straight, level track at a constant speed travels 0.750 km in 20.0 s. The return trip over the same track is made in 25.0 s. (a) What is the average velocity of the car in m/s for the first leg of the run? (b) What is the average velocity for the total trip?
A rugby ball is kicked at an angle of 30° above the horizontal from the top edge of a cliff with an initial speed of 14 m/s. It takes 8 seconds for the ball to travel from the top of the cliff to the ground below. What is the height of the cliff? (Assume air resistance is negligible) answer: 257.6 m
A golf ball is hit off land which is a distance H above a green. The initial velocity is 16.3 m/s at 27.0 degrees above the horizontal. The ball lands on the green 1.94 seconds after it's launched. How much higher (H) is the land from which the ball is launched from the green? Air resistance doesn't have an effect.
A car is parked near a cliff overlooking the ocean on an incline that makes an angle of 19.9◦ with the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline and has a velocity 5 m/s when it reaches the edge of the cliff. The cliff is 44.5 m above the ocean. How far is the car from the base of the cliff when the car hits the ocean in m? The acceleration of gravity is 9.8 m/s2 .
A potato gun fires with a velocity of 20.1 m/s at 27.0 degrees above the horizontal. A wall which is 40.0 m tall sits 17.9 m away. How high above the launch height does the potato strike the wall? Air resistance doesn't have an effect.
