    I am weak in physics. Please help me to solve these problems.

    1. A 16-kg sled is being pulled along the horizontal snow-covered ground by a horizontal force of 24 N. Starting from rest, the sled attains a speed of 2 m/s in 8 m. Find the coefficient of kinetic friction between the runners of the sled and the snow. 2. A dump truck of 2500 kg is being...

    Question about friction ?

    A block whose weight is 45N rests on a horizontal table. A horizontal force of 36N is applied to the block . The coefficients of static and kinetic friction are 0.65 and 0.42, respectively. Will the block move under the influence of the force, and if so, what will be the block's...
