Several children are on a sled pulled by a four-wheeler across a level snow-covered field. The sled is moving at a constant speed of 9.25 m/s, and the tow rope (parallel to the ground) makes an angle of 35.0°, with respect to the velocity of the sled. If the tension in the rope is 42.0 N, determine the work done (in J) on the sled by the tension in the rope in 13.0 s.

Using software, a simulation of a javelin being thrown both on earth and on the moon is created. in both cases, the velocity and angle of projection are kept the same. on earth, the javelin covers a distance y. what distance would it cover on the moon? (the moon’s gravity is about 1/6th that of earth.) a. 6y b. 6/y c. y/6 d. (y+6)2
