QUESTION 6 A 4.0-kg block has an initial velocity of 10 m/s on a level floor. Because of kinetic friction between the block and the floor, it takes 2.0 s for the block to come to rest. What is the coefficient of kinetic friction between the block and the floor? a. 0.38 Ob.0.64 C. 0.25 Od. 0.77 O e. 0.51

Two blocks are attached by a string , and are acted upon by a force F, as shown, The system accelerates in the x direction across a smooth table with an unknown acceleration. The tension in the string between the two masses is 20.0 N. a) What is the value of the acceleration ? L. m,-8.0 kg m=2.0 kg T20.0 N Your Answer: Answer units

24. A pickup truck with mass 980 kg is initially at rest. The truck accelerates to a speed of 95 km/hr within a distance of 60 meters. What the direction and size of the force that acts on the truck? a. b. If the truck were carrying a load of 200 kg, what new force would be required to achieve the same acceleration?

A high jumper with a body weight of 900N exerts an average vertical force of 2150N down on the floor for 0.50 s. The average vertical force exerted on the jumper by the floor is: a. 2150N b.1640N c. 900N d.3050N

A 2.0 kg box is at rest on a flat horizontal surface. A continuously applied force is then exertedon the box. When the applied force just exceeds 5.0N the box then begins to move. Q1. Construct a free-body diagram for the box at the moment when the applied force is 5.0N.     Q2. Determine the magnitude of the peak static friction force and the corresponding coefficientof static friction.
