5.An object with a mass of 5 kg is allowed to slide from rest down an inclined plane. The plane makes an angle of 30° with the horizontal and is 80 m long. The coefficient of friction between the plane and the object is 0.3. Find the speed of the object at the bottom of the plane. Show your work 6. Two blocks joined by a string have masses of 5 and 10 kg. They are on a frictionless horizontal surface. A 2nd string, attached only to the 10 kg block, has a horizontal force of 45 N applied to it. Both blocks accelerate. Find a) the acceleration b)the tension in the string between the blocks. Show your work
