A 4.0 kg bundle starts up a 30 incline with 128 J of kinetic energy. How far will it slide up the incline if the coefficient of kinetic
friction between bundle and incline is 0.30?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
