You often see magicians pulling the tablecloth off a table while there are still plates on it. Surprisingly, the plates are left undisturbed. Explain how this trick is done.
Find the form of expression of the period of vibration of simple pendulum as T=km^x L^y G^2 where k,x,G, and 2 are known terms?
Starting from home, you walked 200.0 m N going to the market. From there, you
proceeded 300.0 m E to a grocery store before walking250.0 m SE to buy computer
parts. You decided then to go to school which is 100.0 m 30O N of E of the computer
shop. Applying the concepts of vector addition using the graphical and component
method, what is your latest location with respect to your house? Show complete
solutions of both methods used.
What is the total distance traveled by and displacement of a runner that
completes 5 rounds in a standard track oval? Explain your answer.
Swimmers A, B, C, and D had a 100-m breaststroke competition on a standard
swimming pool. Swimmer A reached the other end after 10 seconds, B = 12
seconds, C = 13 seconds, and D = 8 seconds. From the other end, swimmer A
reached the finish line after 12 seconds, B = 12 seconds, C = 12 seconds, and D
= 10 seconds. Graph the motion of the swimmers. (3 points for each graph of
each swimmer)

500.0 m if you started from rest?
A rifle bullet can penetrate one plank. If the velocity of the bullet be tripled, how many planks it will penetrate ?
A body of mass 1 kg is thrown vertically upward and the body comes back on the earth surface after 8 s. Find the K. E. and potential energy after 2 s. g = 10 ms².
A block of wood weigh 4newton is placed on a horizontal table .it is then pulled by means of a string if the tension in the string is 2.5newton calculate the coefficient of static friction
There are three ways to bring a 2 kg particle from the origin marked as (0,0) to point C with coordinates (5 m, 5m). Path 1 is along OAC, path 2 is along with OBC, and path 3 is OC. Suppose that the force that will do this work has the following component: Fx = 4N and Fy = 3N. Find the work done by this force in each path. Is this force conservative? What is the coefficient of restitution? Show the equation.
