Q. Many people mistakenly believe that the astronauts orbiting the earth are "above gravity." Compute the acceleration because of gravity, g, for space shuttle territory, 245 kilometres above the earth's surface (dashed line in sketch). Earth's mass is 6 multiplied by 1024 kg, and its radius is 6.38 multiplied by 106 m (6380 km).
A playground is on the flat roof of a city school, 5 m above the street below (see figure). The vertical wall of the building is h = 6.20m high, to form a 1.20 m high railing around the playground.
A professor's office door is 0.95 wide, 2.2 high, 4 thick; has a mass of 22 , and pivots on frictionless hinges. A "door closer" is attached to door and the top of door frame. When the door is open and at rest, the door closer exerts a torque of 5..
What is the period of oscillation of the scale? State your reply numerically in seconds.
An automobile club plans to race a 780 kg car at the local racetrack. The car needs to be able to travel around several 170 m radius curves at 85 km/h. What must the banking angle of the curves be so that the force of the pavement on the tires of the..
the fact that it moves very slowly by sky would probably cause it to be named after Yurtle, the god of turtles.
Find the magnitude of the electron acceleration. Under an influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt.
A 45 kg girl is standing on a 130 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.33 m/s relative to the plank.
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.
What is the maximum reaction time. A 1.52 wide, 1.50 high, 1500 car hits a very slick patch of ice while going 21.0 .If friction is neglected, how long will it take until the car's speed drops to 14.
A coffee filter of mass 1.5 grams dropped from a height of 1 m reaches the ground with a speed of 0.7 m/s. How much kinetic energy Kair did the air molecules gain from the falling coffee filter.
An electric force of 4.0 N exists between two objects separated from each other by a distance of r. If the distance is decreased to 0.50 r, compute the magnitude of the force between the two objects.
The circular top of a can of soda has a radius of 0.029m. The pull-tab has an area of 4.13 10-4m2. The absolute pressure of the carbon dioxide in the can is 1.4 x10^5Pa. Find out the force that this gas generates.
