Q1. Consider a one dimensional elastic collision between a moving object A and an object B initially at rest. How would you select the mass of B, in comparison to the mass of A, in order that B should recoil with the greatest speed?
Q2. A 47 kg block is suspended from a uniform chain that is hanging from the ceiling. The mass of the chain itself is 16kg, and the length of the chain is 1.5m. What is Tension in the chain at the point where the chain is attached to the block? What is the tension of the chain midway up the chain? And find out the tension in the chain at the point where the chain is attached to the ceiling.
A 61.0 kg skier encounters a dip in the snow's surface that has a circular cross section with a radius of curvature of 12.0 m .If the skier's speed at point A is 7.50 m/s (before entering dip), what is the normal force exerted by the snow on the skie..
Determine the tension in each string
You work for a moving company and are given the job of moving two crates (masses are 130kg and 280kg) held together by a rope attached between the two. You pull on a rope attached to the larger crate giving the system the acceleration of 0.29m/s2. Wh..
What should be coefficient of static friction
A block of mass 2.7 kg being released from rest on a 1m frictionless plane, inclined at an angle of 40 degree. The block sided down the inclined and struck second block mass of 3.7 kg. If the two blocks stick together, with what speed would they move..
An insulated Thermos contains 210 cm3 of hot coffee at 88 °C. You put a 19.00 g ice cube at its melting point to cool the coffee. By how many degrees has the coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though..
If she is served 200 of coffee at 85 in a well-insulated container, how much ice at 0 must she add to obtain a final temperature of 33.
What is the total flux
Imagine a "free" electron and a "free" proton held midway between the plates of a charged equivalent plate capacitor. When released, how do their accelerations and directions travel compare.
What is the angular velocity in rad/s . What is the least pressure obtained inside the bottle? What will happen when this pressure is reached.
