Aloaf of bread is removed from an oven and is left sitting in the kitchen to cool. its temperature t minutes after being removed from the oven is given by the equation t(t) = 103e-0.0182t73. find the temperature of the kitchen (assuming the temperature remains constant), the initial temperature of the bread when it is removed from the oven, and the temperature of the loaf of bread after 90 minutes.

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
