QUESTION 3 The 1500-kg rear driving truck reaches a speed of 50 km/h from rest in a distance of 60 m up the 10-percent incline with constant acceleration. Calculate the normal force under each pair of wheels and the effective coefficient of friction between the tires and the road during this motion (Hints: the driving force from the friction of the rear wheels, not from front wheels).

30 m 5. The standard test to determine the maximum lateral acceleration of a car is to drive it around a 70 m - diameter circle painted on a level asphalt surface. The driver slowly increases the vehicle speed until he is no longer able to keep both wheel pairs straddling the line. If this maximum speed is 16 m/s for a 1500-kg car, determine the coefficient of friction between the pavement and the car tires. (10 marks)
Problem 5:A 5-kg block rests on a 30° incline. The coefficient of static friction between the block and incline is 0.20. How large a horizontal force must push on the block if the block is to be on the verge of sliding up the incline?
A 5 kg block rests on a 30 degree incline. The coefficient of static friction between the block and the incline is .20. How large a horizontal force must push on the block if the block is to be on the verge of sliding A) up the incline and B) down an incline Answer: A) 43 N B) 16.6 N What would be the work to get me to this answer?
A 22.0 kg box is sliding down on an incline set at (35.0+A) degrees up from horizontal. The coefficient of kinetic friction between the box and the incline is (B/100). Find the acceleration of the box. Give your answer in m/s2 and with 3 significant figures. A=4 B=11
3: A 10 kg box rests on a 30 degree incline and begins to slide down. (a) what is the acceleration if no friction is present? (b) What is the acceleration if the coefficient of kinetic friction is 0.20? (c) What is the final speed of the box when it reaches the bottom of an incline that is 200 m (use the answer in part b) For problem 3 the input in EXCEL should be: Mass of the box, angle...
A solid sphere rolls in released from rest and rolls down an incline plane, which is 2.0 m long and inclined at a 30° angle from the horizontal. (a) Find its speed at the bottom of the incline. (Remember that the kinetic energy in rolling motion is the translational kinetic energy ½ Mv2 of the center, plus the rotational K.E. ½ Iω2 about the center. Also remember that v = ωr if the sphere rolls without slipping.) (b) Find the...
