Which of following descriptions COULD be true of an object that is at equilibrium or in balanced forces? Select the three true that apply. The object is moving. The object is at rest. The object is slowing down. The object is changing its velocity. The object is accelerating The object is moving with a constant velocity. The object is moving in a circle at a constant speed.

A child who weighs 300 N is swinging on a rope. At the highest point in the swing, the rope makes a 30 degree angle to the vertical. What is the force of tension in the rope?

One of the rides at an amusement park consists of small cars that are supported by steel cables 5.00 m long and rotated in a circle at gradually increasing speed.  As the speed increases, the cars rise.  Find the speed of a car when the cable makes an angle of 35.0 degrees with the vertical.

A car is rounding a turn on a road that is banked at some angle with respect to the horizontal. The road is covered with ice and there is no friction between the road and the tires. which of the following forces is responsible for keeping the car on its circular path? The horizontal component of the force of gravity It is impossible for the car to stay on a circular path in this situation The vertical component of the force of gravity The horizontal component of the normal force The vertical component of the normal force Complete the following sentence. Centripetal forces enable objects to follow circular trajectories with constant speed. enable objects to follow circular trajectories with constant acceleration. O are described by Hooke's law for springs. double in magnitude when an object's speed in uniform circular motion is doubled. OOOO
