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.

On a highway curve with a radius of 46 meters, the maximum force of static friction that can act on a 1,200 kg car going around the curve is 7,500 Newtons. What speed limit should be posted for the curve so that cars can negotiate it safely? [Express the answer in m/s and mph] 17.322 m/s, 38.975 mph 16.956 m/s, 38.151 mph 16.956 m/s, 37.033 mph 16.459 m/s, 37.033 mph 16.956 m/s, 38.975 mph
For a stunt plane flying at a speed of 250 km/h , what is the minimum radius of downward curve a...
Stunt pilots and fighter pilots who fly at high speeds in a downward-curving arc may experience a “red out,” in which blood is forced upward into the flier’s head, potentially swelling or breaking capillaries in the eyes and leading to a reddening of vision and even loss of consciousness. This effect can occur when the non-gravitational part of the centripetal acceleration exceeds 2.5 g’s.For a stunt plane flying at a speed of 250 km/h, what is the minimum radius of...

A thick walled cylinder has a light string
wrapped around its outer radius and rotates
about a horizontal axis. The string then goes
vertically straight up and over a massive
pulley that also rotates about a horizontal
axis, and finally connects to a mass m =
0.900 kg on a rough incline (μk = 0.200) that
is angled at 25.0° to the horizontal.
When the system is released from rest the mass slides down the ramp
a distance of 1.80...
