On a horizontal frictionless frozen lake, a girl (36 kg) and a box (9 kg) are connected to each other by means of a rope. Initially they are 20 m apart. The girl exerts a horizontal force on the box, pulling it towards her. How far has the girl traveled when she meets the box `gt`

A horizontal force F pulls a 20 kg box at a constant speed along a rough horizotal floor. The coefficient of friction between the box and the floor is 0.25. The work done by force F on the block in displacing it by 2 m is

Two skaters A and B of mass 50 kg and 70 kg respectively stand facing each other 6 metres apart. They then pull on a light rope stretched between them. How far each moved when they meet?

A 54kg girl on ice skates on a frozen lake pulls with a constant force on all light rope that is tied to a 41 kg sled. The sled is initially 22m from the girl, and both the sled and the girl start from rest. Neglecting friction, determine the distance the girl travels to the point where she meets the sled.

A horizontal force F pulls a 20 kg box at a constant speed along a horizontal floor. If the coefficient of friction between the box and the floor is 0.25,how much work is done by the force F in moving the box through a distance of 2 m?

A box of mass m=2 kg resting on a frictionless horizontal ground is acted upon by a horizontal force F, which varies as shown. Find speed of the particle when force ceases to act.

Two blocks of masses 40 kg and 20 kg are connected by a wire that has a linear mass density of 1 g//m . These blocks are being pulled across horizontal frictionless floor by horizontal force F that is applied to 20 kg block. A transverse wave travels on the wave between the blocks with a speed of 400 m//s (relative to the wire). the lmass of the wire is negligible compared to the mass of the blocks. the magnitude of F is
