A ball on a string travels once around a circle with a circumference of 2.0  m.  The tension in the string is 5.0  NN.  How much work is done on the ball by tension?

Ramon and Sally are observing a toy car speed up as it goes around a circular track. Ramon says, “The car’s speeding up, so there must be a net force parallel to the track.” Sally replies: “I don’t think so.  It’s moving in a circle, and that requires centripetal acceleration. The net force has to point from the center of the circle to the car.”  Select the correct statement.

A book slides to the right at velocity v.  Which forces are acting on the book?

A block of mass m=2 kg is released from rest and slides down a wedge with an angle of

Block 1, of mass m1 = 5.90 kg , moves along a frictionless air track with speed v1 = 21.0 m/s . It collides with block 2, of mass m2 = 57.0 kg , which was initially at rest. The blocks stick together after the collision.  What is the speed of the blocks after the collision?

Consider the standard curve graph shown below. The graph displays the data collected after measuring the absorbance of six solutions that had known soluble carbohydrate concentrations. Identify the independent variable. you see on Y axis – Absorbance being measured and on X axis . amount of soluble carbohydrate
