A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800.0 N on him. The mass of the losing player plus equipment is 90.0 kg, and he is accelerating backward at 1.25 m/s2. What is the force of friction

A 4.2 kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 2.3 m/s2, find the force exerted by the rope on the bucket.    N ?

The net force applied to a 3 kg mass is 12 N at a 55 degree angle relative to the positive x-axis. Find the x and y components of the object's acceleration. x-component 2.625 m/s? 2.240 m/s? 2.294 m/s² 2.835 m/s² 2.710 m/s? F. А. D. В. Е. C. 2.795 m/s² /--/ y-component 3.162 m/s? 3.936 m/s? 3.034 m/s? 3.239 m/s? 3.947 m/s? F. А. D. В. Е. С. 3.277 m/s²

A 2140 kg car traveling to the west at 17.1 m/s slows down uniformly. How long would it take the car to come to a stop if the force on the car is 8560 N to the east? Let East be positive.Answer in units of s. What is the car’s displacement during the time it takes to stop?Answer in units of m.

A 550-kg sports car accelerates from rest to 125 km/h in 7.20 s. What magnitude force does a 75.0 kg passenger experience during the acceleration? O 494 N 182 N O 422 N O 362 N

A warehouse worker applies a force F to accelerate two crates, mã and mp, to the right along a rough floor. Crate mд has a mass of 4m, crate mp has a mass of m. Choose 1 answer: A F Which is the correct relationship between the applied force F acting on mд and the force mд exerts on mB? B D MA mB The force Facting on my is smaller than the force that mA exerts on MB. The force Facting on my is the same as the force that mA exerts on MB. The force Facting on my is larger than the force that mд exerts on MB. The answer depends on the relative size of the friction force on MA and MB.

A 7.8 kg object undergoes an acceleration of 2.9 m/s^2 A. What is the magnitude of the resultant force acting on it? N B. If this same force is applied to a 4.7kg object, what acceleration is produced? m/s^2

While pushing your 55.0 kg lawnmower across the lawn (μ = 0.100) you notice that the handle makes an angle that is 55.0° below the horizontal. What force must you push the lawnmower with in order to have it accelerate at 2.0 m/s²?

A student attaches a rope to a 32 kg box, and drags it to the left with constant velocity of 1.97 m/s. The tension in the rope is 207 N at an angle of 35.7° to the ground. How much does the box weigh? Find the x and y components of the applied (tension) force: Fx = N. %3D Fy = N. How much friction must be present? How much Normal force must be present? N.
