A ball is traveling at a speed of 14 m/s when it starts rolling up a 20° incline. How long does it take the ball stop rolling up the hill?

A projectile is thrown from the top of a cliff with an initial speed of 25 m/s at an angle of 600 up from the horizontal. If the projectile lands 100 m from the base of the cliff how tall is the cliff?

In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 15.0 m in diameter. It is found that the pilot blacks out when he is spun at 30.6 rpm (rev/min). At what acceleration (in SI units) does the pilot black out? acceleration: 77.01 m/s? Express this acceleration in terms of a multiple of g. acceleration as a multiple of g: 7.858 If you want to decrease the acceleration by 22.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? percent of time change:

A car drives around a circular track of diameter 156 m at a constant speed of 33.0 m/s. During the time it takes the car to travel 102 degrees around, what is the magnitude of the car s average acceleration?      13.96 m/s^2     6.98 m/s^2     12.19 m/s^2     0 m/s^2 CANNOT USE CENTRIPITAL MOTION EQUATION, must calculate average acceleration

A pilot can withstand an acceleration of up to 9g, which is about 88 m/s2, before blacking out. What is the acceleration experienced by a pilot flying in a circle of constant radius at a constant speed of 525 m/s if the radius of the circle is 2510 m?

A car is traveling along a straight highway with a speed of 72 kph (20 m/s) when the driver suddenly applies the brakes just before entering the curved section A-B, REDUCING its speed at a constant rate until it reaches point B. The 90-m long curved section A-B has a constant radius of curvature r. An accelerometer mounted on the car recorded a total acceleration of 1.74m/s² just before the car passes point B. B. I 06 1. Which of the following is FALSE regarding the car's motion along the curved section A-B? Its velocity is decreasing and is tangent to its path. Its tangential acceleration is tangent to its path. Its acceleration is increasing in magnitude. Its normal acceleration is directed towards the center of curvature of the path.

A soccer ball is kicked at a speed of 31.0 m/s at an angle of 41.0 degrees above the horizontal. The ball is in the air for 3.10 s.What is the speed the ball is traveling at when it lands (before the ground stops it)?

A well-thrown football is spinning at 5.9 rev/s. The widest point of the football is at the center of the laces, where the radius is 8.50 cm.  What is the magnitude of the centripetal acceleration of the laces in m/s2?

A ball is rolled horizontally off a table with an initial speed of 0.24 m/s. A stopwatch measures the ball's trajectory time from table to the floor to be 0.30 s. How far away from the table does the ball land? (g = 9.8 m/s2 and air resistance is negligible).

A small child is learning to ride a bike for the first time. Her dad decides it would be a good idea to start her on a small hill. The hill is inclined at 3.40° to the horizontal. The child starts partway down the hill, 4.00 m away from her dad, who stays at the top. She starts to wobble, so her dad sprints toward her from rest with an acceleration of 3.80 m/s2. How far has the child gone before her parent catches her?
