A8.2-kg mass slides down a flat hill that makes an angle of 320 with the horizontal. If friction is negligible, what is the resultant force on the sled?
A block of mass 2.0 Kg is sliding down an inclined plane, as shown (the angle is 30 degrees). If the coefficient of kinetic friction is 0.250, determine the net acceleration of the block down the plane.
A solid ball of mass 2.0 kg rolls down a hill of slope 38 degree without slipping. Find the acceleration of the ball’s center of mass, the frictional force between ball and ground, and the minimum coefficient of static friction needed to prevent slipping.
Questions 1&2 FP 1. A sliding block of mass m 0.25 kg is subject to a force of magnitude 4 N that makes an angle of ф-30 with the horizontal surface. If the coefficient of kinetic friction between block and surface is 0.5, what is the resulting acceleration of the block along the surface Figure 1: Block on incline. 2. A block of mass m - 5 kg is subject to a force of magnitude 20 N that makes an...
rope block A5 kg block is sliding on a horizontal surface while being pulled by a child using a rope attached to the center of the block. The rope exerts a constant force of 26 N at an angle of 0 = 30 degrees above the horizontal on the block. Friction exists between the block and supporting surface (with Hs = 0.21 and 4x = 0.11). What is the horizontal acceleration of the block?
rope block A5 kg block is sliding on a horizontal surface while being pulled by a child using a rope attached to the center of the block. The rope exerts a constant force of 28.33 N at an angle of 0 = 30 degrees above the horizontal on the block. Friction exists between the block and supporting surface (with Mg = 0.23 and Uk = 0.15). What is the horizontal acceleration of the block?
The coefficient of kinetic friction for a block of mass 45 kg sliding down an inclined plane having an angle of 52 degrees to the ground is .03. Calculate the acceleration of the sliding block.
1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...
