A 0.50 kg ball moves from rest without friction down a ramp and then travels around the inside of a circular loop of radius R = 15.0 cm. The initial elevation of the ball on the ramp is h. If the speed of the ball at point B (at a height of 30.0 cm from the ground) is 3.43 m/s, find h.

An automobile traveling at 70.0 km/h has tires of 50.0 cm diameter. (a) What is the angular speed of the tires about their axles? rad/s (b) If the car is brought to a stop uniformly in 40.0 complete turns of the tires (without skidding), what is the magnitude of the angular acceleration of the wheels? rad/s2 (c) How far does the car move during the braking? m
picture. A 2,500 kg truck travels at 72.0 km/h and rounds an unbanked curve of radius 80.0 m. The coefficient of static friction between the tires and the road is 0.700, b. Draw a free-body diagram and show all forces on the truck. Determine the force of friction required to keep the truck in the same lane? What is the maximum speed (in km/h) at which the truck can negotiate the cur safely without going off track? c.

(a) What is the work done on the cart by friction? (b) What is the work done on the cart by the normal force? (c) What is the work done on the cart by the shopper? (4 pts) 2 Calculate the kinetic energies of (a) a 2000.0-kg automobile moving at 100.0...
An airplane is flying in a horizontal circle at a speed of 390. km/h. If its wings are tilted at angle θ = 36.0° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an “aerodynamic lift” that is perpendicular to the wing surface. Use g = 9.81 m/s2.
An airplane is flying in a horizontal circle at a speed of 390. km/h (see the figure). If its wings are tilted at angle θ = 41.0° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an “aerodynamic lift” that is perpendicular to the wing surface. Use g = 9.81 m/s2.
7. A highway curve with a radius of R metres is banked so that cars moving at v m/s around the curve do not have to rely on friction when taking the turn. IWPS 7.
