Besides the gravitational force, a 3.40-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (5.50 - 3.30) m, where the direction of is the upward vertical direction. find the ..
Because the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it should be released above the top of the loop-the-loop height.
A horse is capable of moving at four different speeds: walk (1.9 m/s), trot (5.0 m/s), canter (7.0 m/s), and gallop (12 m/s). Ann is learning how to ride a horse. She spends 15 minutes riding at a walk and 1.8 minutes at each other speed.
