Can someone help me understand this problem? I got an answer of 7.13 seconds but that appears to be inaccurate. It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 70 mph? Suppose that μs=1.00μs=1.00 and μk=0.80μk=0.80. Thank you for your help!
You are quite excited with the lesson in friction that you learned in Physics 1A that you decide to measure the coefficient of kinetic friction of surfaces. You try your idea on a glass surface and a glass cup (mass = 0.15 kg). You set the glass cup moving with an initial speed of 2.8 m/s. After travelling a length of 1 m, it stopped. What then is the coefficient of kinetic friction of the glass-glass surfaces?
A 10 kg box is being pushed across a rough surface with a constant speed of 2 m/s. The person pushing the box slips and stops pushing. The box continues to slide across the surface before coming to rest. If the coefficient of friction between the crate and the surface is 0.1, how far does the box travel before coming to rest?
a 2000-kg car initially at rest is held by a friction force that can resist up to 1200 N. If the person can push with a force of 500 N, how many seconds will it take for the car to reach a speed of 1 m/sec?
A rocket sled accelerates to 41 m/s. When the rocket engine stops, the sled skids along its rails. If the coefficient of friction is 0.5 and its mass is 1000 kg, how fast is the sled moving after 2.2 s?
A 5000 kg lorry gradually accelerates from rest. There is a box of mass 200 kg on the back of the lorry. The box is not tied to the lorry. The lorry accelerates from rest to a speed of 15 m/s over a certain distance. The maximum frictional force between the lorry and the box is 630 N. The maximum acceleration (in m/s^2) that the lorry can have without the box falling off is: О 3.15 O 15 O 0.126 O10 uo l1:00 ENG 4)
A car has a mass of 1750 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 6500 N. If the car is moving at 22 m/s, what is the shortest distance in which the car can stop safely?
A block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a friction force stops the block in a distance d. The block's initial speed v0 is 6.9 m/s, the height distance h is 1.1 m, and uk is 0.60. Determine d. Use g=9.8 m/s/s.
An object with a mass of 1.76 kg is initially at rest upon a horizontal, frictionless surface. An applied force of 3.04 N i acts on the object for 2.08 s. What is the object's final speed? Enter a number rounded to 2 decimal places and assume the answer has proper SI Units.
John and Peter were pushing a 2000 kg car and it reached a speed of 3.0 m/s after starting from rest. It covered a distance of 10 meters. What is the amount of force (Newton) exerted by John and Peter if the coefficient of kinetic friction is 0.100 ?
You have devised an experiment to measure the kinetic coefficient of friction between a ramp and a mass. You place the mass on the ramp at an angle high enough that the mass starts sliding. You measure the time it takes to fall down a known distance. The time it takes to fall down the 45 degree ramp starting from a standstill is At = 0.46 sec, m=1 kg, and the distance it falls, Ax , is 0.5 m. What is µk? m Дх in At Uk
Two horses pull a cart with a total applied force of 1000N. The kinetic friction from the gravel road has a value of 375 N. Assuming the cart is 200kg, what is the acceleration of it?The road is flat and the horses are traveling in a straight path.
