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 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
Questions about a 700 kg car: 1.) What is the work required (in J) to stop the car if it is going 20 m/s and stops in a distance of 35m? 2.) Now suppose the car were traveling 40 m/s. What is the work required (in J) to stop it? 3.) What distance (in m) is required for the car in the previous provlem to stop when traveling 40 m/s? Thanks
A car of mass 2.0 x 103 kg is initially moving at 75 km/h when the brakes are applied and the car is brought to a stop in 25 m. Assuming the force that stops the car is constant, find the magnitude of that force that stop the car. A. - 15.73x103 N B. -17.3x103 N C. 16.73x103 N D. 12.73x103 N
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?
1a . A constant force of 32.3 N pulls on a 20 kg block on a horizontal surface. The force is directed at 30o above the horizontal. A friction force impedes the motion. If at the start of the motion the block was at rest and after 11 meters it has a velocity of 3, what is the coefficient of friction? 1b. What is the work done by the constant force when the block is moved 8 meters? 2.What constant,...
In an emergency stop to avoid an accident, a shoulder strap seat belt holds a 51.5 kg passenger firmly in place. If the car were initially traveling at 85.0 km/h and came to a stop in 6.1 s along a straight, level road, what was the magnitude of the average force applied to the passenger by the seatbelt?
To stop a 2500 kg car traveling at 17 m/s in a time of 9 s requires an average force of magnitude? Select one: O A. 2400 N O B. 2.73 KN O C. 24.53 KN O D. 4.72 KN
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...
