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.
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 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...
(a) Calculate the force (in N) needed to bring a 850 kg car to rest from a speed of 90.0 km/h in a distance of 105 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).
(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 car of mass 1000 Kg descends a hill inclined with horizontal by 30°, the car is traveling at 80 km/h is uniformly brought to rest over a distance of 40 m. Calculate using work-energy method the average braking force required. The resistance to the motion is 200 N. 40 0 = 30°

3. An engine exerts a force of 10000 N on a 1000 kg car travelling over a flat road. The force (overcoming friction) accelerates the car from rest such that it travels a distance of 50 m in 5 s Find e. the net acceleration of the car, f. normal force exerted by the road on the car, and g. the coefficient of kinetic friction between the car and the road? 4. A 10 kg block is initially at rest...
(a) Compute the impulse necessary to bring to rest the 47.0 kg driver of an automobile initially moving at 26.0 m/s. (b) Find the average force on the driver if the deceleration is accomplished gradually by the application of brakes over a 11.6 s interval. (c) Find the average force if the car is stopped in a collision that brings the driver's seat to rest in 0.100 s, assuming the driver is restrained by a seat belt. What are the...
