Q. A 0.450-kg hockey puck, moving east with a speed of 4.20 m/s, has a head-on collision with a 0.900-kg puck initially at rest. Assuming a perfectly elastic collision, what will be the speed and direction of each object after the collision. A ball of mass m makes a head-on-elastic collision with a second ball (at rest) and rebounds with a speed equal to one-fourth its original speed. What is the mass of the second ball?
Q. An astronaut applies a force of 500 N to an asteroid, and it accelerates at 7.00 m/s2. What is the asteroid's mass?
Black oil reservoirs at 250 deg F+, can there be oil cooking going on releasing some of the light and or intermediats that result in some disequilibreum under reservoir conditions (Pb vs depth could be as high as 70 psi/ft)
A 1600 kg car starts from rest at A, coasts 180m through a dip and comes to stop at B after coasting a distance d on level ground. If the rolling resistance is a constant force of 280N, conclude the distance d.
Compute the average linear velocity of the discus
If a 200 N force F1 is applied to the piston with the 4 cm diameter, Calculate the magnitude of the force F2 that can be resisted by the piston with the 10 cm diameter? Ignore the weights of the pistons.
An astronaut travels to an alternate universe that contains infinite charged plane and no other charged objects. The astronaut observes that the electric field in this universe has a magnitude of 1.20 N/C everywhere and points directly away from the ..

If a 4-engine jet accelerates down the runway at 5m/s2 and 3 of the jet engines fail, how much acceleration will the other one produce.
What was the average acceleration throughout the trip
A stunt pilot performs a circular dive of radius 715m. At the bottom of the dive pilot has a speed of 265 m/s which at that instant is increasing at a rate of 15 m/s2(along the direction of vector B) What total acceleration does the pilot have at ..
A gymnast of mass 69.0 kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 for the acceleration of gravity.
