ANSWER ONLY 4. READ THE INSTRUCTIONS PROBLEM SETS: FRICTIONSolve what is asked the given problems. Show compiete process and box the final answer. Round offfinal answer to the nearest hundredths.1. A force of 50N is needed to push a 250N load on the floor, what is the coefficient of friction?2. A 50-kg box is pulled with uniform speed along a horizontal floor by a force parallel to the floor.The coefficient of friction is 0.30. find the magnitude of the force.3. A 50-kg box is placed on an inclined plane making an angle of 30 ° with the horizontal. If thecoefficient of kinetic friction is 0.3, what is the resultant force on the box?4. A 15 -kg box is placed on an inclined plane making an angle of 5° with the horizontal, Calculatethe force needed to pull the mass up the plane if the coefficientof kinetic friction is 0.20.5. A box is given a push so it slides with the horizontal floor. If the coefficient of kinetic friction is0.2 and the push gives the box an initial velocity of 4m/s, how far will the box go?6. How much force is needed to keep a 1200-kg car moving at constant velocity on a level concreteroad? (uk= 0.04)7. A force of 200 N is just sufficient to start a 50 kg steel trunk moving across a wooden floor. Findthe coefficient of static friction.8. A 40 kg wooden crate is being pushed across a wooden floor with a force of 160 N. If uk= 0.3,find the acceleration of the crate.9. A bowling ball with an initial velocity of 3m/s rolls along a level floor for 50 m before coming tostop. What is the coefficient of rolling friction?10. The coefficient of kinetic friction and wet concrete road is 0.5.a. Find the minimum time in which the car whose initial velocity is 50km/h can come to astop on such a road.b. What distance will the car cover in this time?
