Please help A 1.0 times 10^3 kg car is being raised at a constant speed by...
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...
A 1160-kg car is being pulled up a frictionless ramp at a constant speed, as shown in the figure. (Figure 1) The cable makes an angle of 31.0° above the surface of the ramp, and the ramp itself rises at 25.0° above the horizontal. Find the tension in the cable How hard does the surface of the ramp push on the car?
A 1200-kg car is being raised with a constant acceleration of 2.53 m/s2 by a crane, using a 20-m long steel cable that is 1.5 cm in diameter. Young's modulus for steel is 2.0 × 1011 N/m2. What is the change in length of the cable caused by lifting the car?
A tugboat tows a barge at constant speed with a 3800-kg cable, as shown in the figure Part A.)If the angle the cable makes with the horizontal where it attaches to the barge and the tugboat is 22 ∘ , find the force the cable exerts on the barge in the forward direction.
please ansa all A car travels around a curve with constant speed. The correct statement from the following is the car has an acceleration directed inward toward the center of the curve. the velocity of the car is constant. the car has an acceleration direction outward from the center of the curve. the car has zero acceleration. the car has an acceleration directed in the instantaneous direction of the velocity vector. A ball is whirled on the end of a...
A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...
A 15,000 N crane pivots around a friction-free axle at its base and is supported by a cable making a 25∘ angle with the crane (Figure 1). The crane is 16 m long and is not uniform, its center of gravity being 7.0 m from the axle as measured along the crane. The cable is attached 3.0 m from the upper end of the crane. When the crane is raised to 55∘ above the horizontal holding an 11,000 N pallet...
A 23 kg suitcase is being pulled by its handle at a constant speed across level ground. The suitcase handle is at an angle of 25 degrees above the horizontal. If the normal force exerted on the suitcase is 180 N, what is the magnitude of the force being applied to the handle?
A 26 kg suitcase is being pulled with constant speed by a handle that is at an angle of 27 ∘ above the horizontal Part A.) If the normal force exerted on the suitcase is 160 N , what is the force F applied to the handle?
