Calculate the force (in N) needed to bring a 1100 kg car to rest from a speed of 95.0 km/h in a distance of 100 m (a fairly typical distance for a non-panic stop). b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a). force in (b) force in (a)
(a) Calculate the force needed to bring a 1050 kg car to rest from a speed of 95.0 km/h in a distance of 115 m (a fairly typical distance for a nonpanic stop). (b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a), i.e. find the ratio of the force in part(b)...
(a) Calculate the force needed to bring a 900 kg car to rest from a speed of 90.0 km/h in a distance of 100 m (a fairly typical distance for a nonpanic stop). N (b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a), i.e. find the ratio of the force in...
Determine the force to bring a 1500 kg car to rest if it was initially moving at 50 mph over a distance of 45 m.
QUESTION 1 15 points Save An Calc?late the force (in N) needed to bring a 1000 kg car to rest from a speed of 90.0 km/h in a distance of 115 m (a fairly typical distance for a non-panic stop).
Use the work-energy theorem to determine the force required to stop a 1100-kg car moving at a speed of 25.0 m/s if there is a distance of 55.0 m in which to stop it.
calculate the distance required for a 1700 kg car to come to rest from a speed of 35 m/s when 2900 N of force is applied by the brakes
A roller coaster car of mass 800 kg when released from rest at point A (height h above the ground) slides along the track and inside the loop of radius 16.0 m. The car never loses contact with the track. A) Draw below a free body diagram for the car the car at the top of the loop. B) If the normal force acting on the car at the top is 1500 N, what is the speed of the car...
