Several children are on a sled pulled by a four-wheeler across a level snow-covered field. The sled is moving at a constant speed of 9.00 m/s, and the tow rope (parallel to the ground) makes an angle of 35.0° with respect to the velocity of the sled (see the figure below). If the tension in the rope is 38.0 N, determine the work done on the sled by the tension in the rope in 12.0 s.
If you lie on the ground at night with no cover, you get cold rather quickly. Much of this is due to energy loss by radiation. Estimate the net rate at which your body loses energy by radiation to the night sky under these conditions
I place a 4cm-high object 10cm in front of a 10cm focal length concave lens. How tall is the image
An object weighting 100N is traveling vertically upward from the ground in the absence of air resistance at a constant velocity of 5 m/s
A flight attendant pulls her 61N flight bag a distance of 279m along a level airport floor at a constant velocity. The force she exerts is 41N at the angle of 50° above the horizontal.
A disk is reputed to accelerate from 0 to 389 RPM in 3.5 seconds. How many radians does it turn through.
A high-speed drill reaches 2000 rpm in 0.50 s. What is the drill's angular acceleration? Through how many revolutions does it turn during this first 0.50s.
a blue cart (mass=0.400kg) makes an elastic collision with a red cart (mass=0.750kg), How much kinetic energy is lost in the collision
A coin placed on a turntable rotating at 36.1 rev/min will stay there if its center is placed no further than 7.1cm from the axis of rotation. find the maximun distance the center of the coin can be placed
A turtle ambles leisurely-as turtles tend to do-when it moves from a location with position vector r1,x = 1.49 m and r1,y = -2.77 m in a lettuce garden to another location, find the magnitude of the turtle\'s average velocity
Two charges are placed on the x axis. One of the charges q1= +8.5 C is at x1 = + 3.0 cm and the other q2= -21C is at x1 = + 9.0 cm. Find the net electric field (magnitude and direction) at.
Our solar system is about 1.34 parsecs away from planet A. An astronaut is moving away from earth toward planet A at 0.80c as measured in the earth's reference frame. What frequency of light is observed by the earthlings
150g of steam at 100C (373K) is injected into a container containing 250g of ice and 150g water both at 0C (273K). What is the change in entropy of the environment
