![]() ![]() If the same net force F acts on an objectĪ. A net force F acts on an object of mass m, causing it toĪccelerate at 4.0 m/s2. Of apples, causing it to accelerate over level ground at 1.8įind the coefficient of friction between the carton and theġ5. A student exerts a 120 N horizontal force on a 25 kg carton What minimum horizontal force F will just prevent the 5.0 kgīlock from sliding if the coefficient of friction between the wallġ4. If a net force does act on an object, the object willĪccelerate in the direction of the net force.ġ3. The acceleration of freely falling objects is proportional toĭ. Rest, or continue to move at a constant velocity.Ĭ. If no net force acts on an object, the object will remain at For every action force, there is an equal and oppositeī. Which of the following is not a statement of one of Newton’sĪ. Which equation is a form of Newton’s second law?ġ2. What is the coefficient of friction between the toboggan andġ1. A 45 kg toboggan and rider decelerate on level snow at 0.53 If the scale reads 850 N, what is the magnitudeĪ. A 75 kg man stands on a scale while accelerating upwards inĪn elevator. WhatĪcceleration would force F give to the two masses m1 and m2 if theyĪ. The sameįorce F gives mass m2 an acceleration of 2.0 m/s2. Force F gives mass m1 an acceleration of 4.0 m/s2. Kg object falling vertically with an acceleration of 8.5 m/s2 ?Ĩ. What is the frictional force due to air resistance on a 0.50 A constant force is applied to an object on a frictionlessĬ. An object is sliding down a smooth incline. ![]() A 3.00 kg object is being accelerated vertically upwards atĥ. What is the tension in the rope during the acceleration?Ĥ. A 2.00 kg object, initially at rest on the ground, isĪccelerated vertically by a rope, as shown. The coefficient of friction between the block and the surface?ģ. The applied force is 500 N and the friction force is 300 N. A 65.0 kg block is being accelerated along a level surface. Unless acted on by an external net force, an object will stayĪ. A constant force is applied to an object on a frictionless surface, as shown in the diagram below. If friction is negligible, the object has A. A 3.00 kg object is being accelerated vertically upwards at 2.80 m/s 2, as shown. What is the tension in the rope during the acceleration? A. The object reaches a height of 3.00 m in 1.50 s. A 2.00 kg object, initially at rest on the ground, is accelerated vertically by a rope, as shown. What is the coefficient of friction between the block and the surface? A. continue to move in a straight line at a constant speed. Unless acted on by an external net force, an object will stay at rest or A. ![]()
