Q1. A train is travelling up a 4.60 incline at a speed of 2.45 while the last car breaks free and begins to coast without friction. How long does it take for the last car to come to rest momentarily?
Q2. Do you agree with IBM's employment response to competition from software development contractors in India, like Wipro, that are expanding into IT consulting services? Why or why not?
A 0.04 kg bullet collides in elastically with a 0.5 kg ballistic pendulum. Before the collision the pendulum was at rest but immediately after collision the pendulum is moving with speed of 13.6 m/s. How fast was the bullet travelling before the coll..
A block of mass m = 4.2 kg, moving on a frictionless surface with a Vi=2.9m/s speed makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.2 block recoils with a speed of 0.9m/s. The mass M is closest to.
Assume that a binary star system consists of two stars of equal mass. They are observed to be separated by 310 million kilometres and take 4.0 Earth years to orbit about the point midway between them.
How much farther from the tower does the cannonball from the higher cannon land than cannonball from the lower cannon.
A car of mass = 1400 travelling at 60.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and the car's tires. Use = 9.80 throughout this problem.
After being accelerated to a speed of 1.84×105, the particle enters a uniform magnetic field of strength 1.00 and travels in a circle of radius 35.0. The results of this experiment allow one to find.
