Two bodies hang on a string 2.1m long. The two bodies have a mass of 3.75kg and 2.4kg respectively. If the 3.75kg mass is raised to a height of 0.545m and released, and if upon impact the mass adhere.

•Mass1 = 3.75 kg
•Mass2 = 2.4 kg
•String length = 2.1 m
•M1 raised = 0.545m

a) Find the velocity of the 3.75kg mass before impact.
b) Find the common velocity of the mass after impact.
c) Find the lost of kinetic energy on impact.
d) Find the height through which the center of gravity of the system will rise.
e) Find the tension on the string of the 3.75kg mass before impact.

To quote one of our very good math and science tutors: “You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.”

2. Tell your friends daniel, luc and michel that the subject is spelled physics, not physic.

A "physic" is a laxative.

3. A dynamite blast at a quarry launches a rock straight upward, and 1.6 s later it is rising at a rate of 12 m/s. Assuming air resistance has no effect on the rock, calculate its speed (a) at launch and (b)5.3 s after launch.

4. Two bodies of masses 0.8 kg and 1.2 kg are located at (1,-2) and (-3, 4), respectively. Find the co-ordinates of the ...
