Questions about a 700 kg car: 1.) What is the work required (in J) to stop...
The distance required for a car to come to a stop will vary depending on how fast the car is moving. Suppose that a certain car traveling down the road at a speed of 20 m/s can come to a complete stop within a distance of 80 m. Assuming the road conditions remain the same, what would be the stopping distance required for the same car if it were moving at speeds of 10 m/s, 40 m/s, or 5 m/s...
17) Determine the work, in J, required to stop a 1500-kg car traveling at 30 m/s. (hint: use the work-energy theorem). a) 2.4 x 105 b) 8.2 x 105 c) 1.7 x 105 d) 6.8 x 105 Answer_______________ 18) 10 J of heat are removed from a gas sample while it is being compressed by a piston that does 30 J of work. Determine, in J, the change in thermal energy of the system. a) 4 b) 10 c) 20...
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.
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)
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 700 kg car is waiting at a stop light, when a 1200 kg car coasting at 4.0m/s strikes it from the rear. the cars do not stick together, nor is the collision perfectly elastic. The front car moves ahead at 5m/s after the collision. What is the speed of the rear car after the collision?
Part A - A car traveling at 11.4 m/s skids to a stop in 10.7 m from the point where the brakes were applied. In what distance would the car have stopped had it been going 34.2 m/s, if tires and road condition were unchanged (i.e. if the acceleration were the same)? 32.1 m 96.2 m 53.4 m 72.2 m
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.
A 750 kg car slows to a stop from traveling southbound at 30 m/s over a distance of 500 m. What was the acceleration needed to stop the car? How large was the force required to stop the car? Two cables are being used to pull a 100 kg sled on a frictionless surface. The first cable has a tension of 500 N in a direction 15o south of east. The other cable has a tension of 800 N in...
What is the magnitude of the average force required to stop in 1800 kg car in 7.0 seconds if the car is traveling at 95 km/hours? Express your answer using two significant figures. Could you please look at my problem that I attempted to solve (attached) and advise what I did wrong. d 11000 Dou 1oo0 End
