An advertisement claims that a particular automobile can "stop on a dime". What net force would actually be necessary to stop an automobile of mass 960 kg traveling initially at a speed of 57.0 km/h in a distance equal to the diameter of a dime, which is 1.8 cm ?
(c7p50) A 900- kg car collides with a 1400- kg car that was initially at rest at the origin of an x-y coordinate system. After the collision, the lighter car moves at 30.0 km/h in a direction of 30 o with respect to the positive x axis. The heavier car moves at 33 km/h at -46 o with respect to the positive x axis. What was the initial speed of the lighter car (in km/h)? What was the initial direction...
On vacation, your 1400 kg car pulls a 580 kg trailer away from a stoplight with an acceleration of 2.20 m/s^2 What is the net force exerted by the car on the trailer? Assume that the positive x axis is directed toward the direction of motion. What force does the trailer on the car? Assume that the positive x axis is directed toward the direction of motion.

1) What average force is required to stop a 150-kg bike in 2.0 s if it is traveling at 25 km/h (**Needs to be in m/s) 2) What average force is required to stop a 950-kg car in 9.2 s if the car is traveling at 95 km/h (**Needs to be in m/s)
A car with its driver has a mass of 1400 kg. It brakes until it reaches rest from a speed of 86 km/h, covering a distance of 180 m. What is the resulting frictional force (external f) that the road exerts on the tires during the process, if we assume that the tires do not slide?
What average force is required to stop a 950 -Kg car at 95 Km/h?
What average force is required to stop a 1700 kg car in 9.0 s if the car is traveling at 85 km/h ? Express your answer to two significant figures and include the appropriate units. Enter positive value if the direction of the force is in the direction of the initial velocity and negative value if the direction of the force is in the direction opposite to the initial velocity.
What average force is required to stop a 1900 kg car in 8.0 s if the car is traveling at 100 km/h ? Express your answer to two significant figures and include the appropriate units. Enter positive value if the direction of the force is in the direction of the initial velocity and negative value if the direction of the force is in the direction opposite to the initial velocity.
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)
