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

A small piece of Styrofoam packing material is dropped from a height of 2.50 m above the ground. Until it reaches terminal speed, the magnitude of its acceleration is given by a = g - Bv. After falling 0.400 m, the Styrofoam effectively reaches terminal speed, and then takes 5.10 s more to reach the ground. (a) What is the value of the constant B? s-1 (b) What is the acceleration at t = 0? m/s² (down) (c) What is the acceleration when the speed is 0.150 m/s? m/s² (down)

A wrench is dropped from the top of a tall tower. It takes 3.07 s to reach the ground. How tall is the tower, in meters? Assume the wrench’s initial velocity is zero, use 9.80 m/s2 as the acceleration due to gravity, and assume air drag does not matter.

Would the answer be "tangent to the curve in the forward direction?" thank you!

A 1.2 kg ball on a string is traveling in an 4.3 m vertical circle with a speed of 2.3 m/s.  Determine the tension (T) in the string at the bottom of the circle.  Use g = 10 N/kg.
