A 1500 kg car is moving at a speed of 25 m/s at the bottom of a semicircle hill of radius 50 m. What is the apparent weight of the car?
4. A 76-kg car driver reaches the bottom of a hill moving at a speed of v= 20 m/s. This bottom of the hill forms the arc of a circle whose radius is 200 m, as shown. (a) At this bottom of the hill, what is the magnitude /r = 200 m of the centripetal acceleration of the driver? (b) Find the force exerted on the driver by the car seat at this bottom of the hill. [(a) 2 m/s;...
In order to stop a 1500 kg car that is originally moving at 25 m/s, and if the car stops over a distance of 50 m, what average force must act on the car?
A 1200-kg car is moving at 19 m/s due north. A 1500-kg car is moving at 18 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. Determine the speed and direction of the combined two-car wreck immediately after the collision. direction North of East
A 1500-kg car is moving westward with a speed of 20m/s and a 3000-kg truck is traveling east with a speed of 16 m/s. Find the velocity of the center of mass of the system. Let east be the positive x-direction.
A 1200-kg car is moving at 16.0 m/s due north. A 1500-kg car is moving at 20.0 m/s due east. The two cars simultaneously approach an icy intersection where, with no brakes or steering, they collide and stick together. 1) Determine the speed of the combined two-car wreck immediately after the collision. (Express your answer to two significant figures.) m/sm/s 2) Determine the direction of the combined two-car wreck immediately after the collision. (Express your answer to two significant figures.)
You
are traveling in a car in a hilly road travelling at a speed of
13.3m/s. Let's pretend that the hills and valleys can be
represented as circles of radius 40m. What is your apparent weight
at the top of the hill and at the bottom of the valley? Assume a
mass of 70kg (an average of the typical adult male and feme masses)

a 1500 kg car moves at a speed of 5m/s around a circle of radius 45m. a) what is the weight of the car ? b) what is the centripetal acceleration experienced by the car? c) what is the resulting centripetal force experienced by the car ?
A 53.8 kg passenger in a roller coaster car goes through the bottom of a 13.9 m radius loop and measures their apparent weight to be 901 Newtons. 1600 m = 1 mile 3600 s = 1 hr What speed did the rider go through the bottom of the loop?
A
1000kg car moving at 15m/s to the right collided head-on with
another 1500 kg car who was coming in the opposite direction at a
speed of 20m/s. After collision the two cars interlocked to each
other, and the wreckage dragged with a new speed. What is the lost
of kinetic energy during the collision ?
