A 1.00 kg object is attached to a horizontal spring. The spring is initially stretched by 0.200 m, and the object is released from rest there. It proceeds to move without friction. The next time the speed of the object is zero is 0.500 s later. What is the maximum speed of the object?
At time t = 0 s, a puck is sliding on a horizontal table with a velocity 3.60 m/s, 35.0° above the +x axis, What is the velocity of the puck at time t = 1.50 s
A bus is traveling up a hill at a speed of 34m/s. The hill is 23 degrees relative to horizontal and the coefficient of static friction between the bus's tires and the road is 0.6. What is the car's minimum breaking distance?
A child, hunting for her favourite horse, is running on the ground around the edge of a stationary merry-go-round. The angular speed of the girl has a constant value of .250 rad/sec.
