Consider a frictionless track as shown in Figure P6.54. A block of massm1= 5.00 kg is released from width=. It makes a head-on elastic collision at width=with a block of massm2= 10.0 kg that is initially at rest. Calculate the maximum height to whichm1rises after the collision
Suppose you are riding a stationary exercise bicycle, and the electronic meter indicates that the wheel is rotating at 9.50 rad/s. how far would you have gone if the bike could move
Calculate the y-component of the magnetic force. How fast must the candy bar travel to have the same joules in the form of kinetic energy.
In the process of changing a flat tire, a motorist uses a hydraulic jack. She begins by applying a force of 59 N to the input piston, which has a radius r1. As a result, the output plunger, which has a radius r2, applies a force to the car. The ra..
You are driving your car and the traffic light ahead turns red. You apply the brakes for 2.5s and the velocity decreases to +4.62 m/s. What is the cars deplacement
A supertanker (mass 1.70 x 10^8 kg) is moving with a constant velocity. Its engines generate a forward thrust of 7.40 X 10^5 N. Determine a) the magnitude of the resistive force exerted on the tanker by water and b) the magnitude of the upward buoyan..
What is the final temperature of the heating element
Does it travel at the same speed the entire time?
A resistor has a resistance R, and a battery has an internal resistance r. When the resistor is connected across the battery, ten percent less power is dissipated in R than would be dissipated if the battery had no internal resistance. Discover the r..
A plank 2.00 cm thick and 14.9 cm wide is firmly attached to the railing of a ship by clamps so that the rest of the board extends 2.00 m horizontally over the sea below. find the shear modulus of the wood
A metal ball of mass 0.66 kg with initial temperature of 30oC is dropped in to a container of 1.08 kg of water at 20oC. If the final temperature is 20.4 oC, what is the specific heat of the metal to the nearest tenth of aJ/kg·K?
A Van de Graa? generator has a potential di?erence of 2.35 MV between the belt and the outer shell. What minimum power is needed to drive the moving belt
