Please answer this all question thank you.
Knowledge and Understanding
A concrete block is pulled 7𝑚 across a
frictionless surface by means of a rope. The tension in the rope is
40𝑁, and the work done by the block is 247𝐽. What angle does the
rope makes with the horizontal?
A 38 N force is applied to a cart. The direction of the
force is the same as the direction of the motion of the cart. If
the cart moves 20 meters, how much work is done by the applied
force?
