A 5000g block slidong down an 1 meter high incline crashed into a spring at the bottom of the incline. Given that the spring constant is 50n/m, determine the length of springs compresion after the collision with the block.
A cyclist uses 27,000 joules per minute (this is about 385 food Calories per hour) to cycle at a constant pedaling rate of 450 radians per minute along a flat road using a gear ratio of 4
Bob connects a lamp of 34 Ohms resistance across a car battery of 12 volts. what would be the power dissipated by the lamp
Earth's radius is 6.38 x 106 m, and it completes one revolution every day. What is the tangential speed of a person standing on the equator?
A 2150 kg satellite is in a circular orbit 780 km (780 x 103 m) above the surface of the earth. What is the gravitational force on the satellite due to the earth? What is the speed of the satellite in its orbit? What is the period of the orbit?
A proton moves eastward in the plane of Earth's 5x10^-5 T magnetic equator so that its distance from the ground is constant. What is the speed of the proton?
q1. a projectile is fired horizontally from a gun that is 48.0 m above flat ground emerging from the gun with a speed
A zero-resistance rod sliding to the right on two zero-resistancerails separated by the distance L = 0.75 m. The rails are connected by a 15.1-Ω resistor, and the entire system is in auniform magnetic field with a magnitude of 0.750 T.
A 200 g ball on a 60 cm long string is swung in a vertical circle about a point 200cm above the floor. The tension in the string when the ball is at very bottom of the circle is 4.4 N.
Global Circulation Models typically have grids of 100-300km on a side. There are obviously lots of atmospheric processes that occur at smaller scales than this. Convection, cloud formation, the effect of mountains...
