A horse pulls a cart horizontally with a force of 60lb at an angle of 30o above the horizontal and moves along at a speed of 8mile per hour. How much does the horse do in 15minutes and what is the power of output of the (1hp = 550ft-lb/s), (1mile = 5280ft).

•• 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?
