(a) Calculate the force needed to bring a 1100 kg car to rest from a speed of 90.0 km/h in a distance of 125 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) to the force in part(a).

AT an accident scene on a level road, investigators measure a car's slid mark to be 78 m long. It was a rainy day and the coefficient of friction was estimated to be .30. (a) Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes. (b) Why does the car's mass not matter? (c) What is wrong with a car that skids?
At an accident scene on a level road, investigators measure a car's skid mark to be 78 m long. It was a rainy day and the coefficient of friction was estimated to be 0.30. use these data to determine the speed of the car when the driver slammed on (and locked) the brakes. (why does the car's mass not matter?)
A person jumps from the roof of a house 3.9-m high. When he strikes the ground below, he bends his knees so that his torso decelerates over an approximate distance of 0.70 m. If the mass of his torso (excluding legs) is 42 kg. find (a) his velocity just before his feet strike the ground, and (b) the average force exerted on his torso by his legs during deceleration.
A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package after the worker pushes it and just as it begins to coast. 0.625 m/s 0.759 m/s 0.600 m/s 0.510 m/s 0.802 m/s 0.641 m/s
You went on a drive late at night after having a fun party with the member of your company when you accidentally hit another car. The investigator observes a skid marks 25m long left by your 1500kg car. Your car skidded to stop on a concrete highway having a coefficient of kinetic friction with the tires of 0.80. Estimate your car's speed at the beginning of the skid?
a 925-kg pick up decelerates to rest from a speed of 97.5 km/h in a distance 125 m. Suppose the pick up is initially traveling in the positive direction. suppose instead of breaking that the pick up hits a concrete abutment at full speed is brought up to a stop at 2.0 m. Calculate the force in newtons exerted on the pickup in this case.
An airboat with mass 3.5 x 102 kg including passengers has an engine that produces a nethorizontal force of 7.70 x 102 N, after accounting for forces of resistance. (a) Find for theacceleration of the airboat (b)starting from rest, how long does it take the airboat to reach aspeed of 12.0m/s? (c)after reaching this speed, the pilot turns off the engine and drifts to a stopover a distance of 50.0 m. Find the resistance force, assuming its constant. Suppose the pilotstarting again from rest, opens the throttle partway. At a constant acceleration, the airboat thencovers a distance of 60.0 m in 10.0 s. Find the net force acting on the boat.
