A child on a sled is initially at rest on an icy horizontal surface. The sled is pushed until it reaches a final velocity of 6.45 m/s in a distance of 10.8 m. The coefficient of friction between the ice and runners of the sled is 0.200, and the weight of the child and the sled is 345 N. Find the work done by the force pushing the sled.
Find the minimum initial speed of a projectile in order for it to reach a height of 1887 km above the surface of the earth.
An elevator car of mass 850 kg falls from rest 3.20 m, hits a buffer spring, and then travels an additional 0.450 m, as it compresses the spring by a maximum of 0.450 m. What is the force constant of the spring?

Problem 4 A child on a sled slides (starting from rest) down an icy slope that makes an angle of 15 with the horizontal. After sliding 20 m down the slope, the child enters a flat, slushy region, where she slides for 2.0s with a constant negative acceleration of -1.5 m/s with respect to her direction of motion. She then slides up another icy slope that makes a 20 angle with the horizontal. (a) How fast was the child going...

Work A child pulls a 5 kg sled along a horizontal surface The child exerts a force of 15 N to 30% and the coefficient of kinetic friction is 0.1 (a) Get the work done by all the forces that feel the sled after moving 3m (b) get the speed of the sled assuming that part of the rest using the Work-Energy Theorem
A child applies a force F parallel to the z-axis to a 6.00 kg sled moving on the frozen surface of a small pond
A child applies a force F parallel to the z-axis to a 6.00 kg sled moving on the frozen surface of a small pond. As the child controls the speed of the sled, the 2-component of the force she applies varies with the 2-coordinate of the sled as shown in figure (Figure 1). Suppose the sled is initially at rest at x = 0. You can ignore friction between the sled and the surface of the pond. For related problemsolving tips...
