o Relative to other parts of the world, would your local ecosystems be affected more or less?
Find out the vertical component of the reaction force
A 21g particle is moving to the left at 29 m/s. How much work must be done on the particle to cause it to move to the right at 41 m/s.
Compute the y-component of acceleration
When subject to a steady acceleration of 0.800 g, the object must be located 0.600cm from its equilibrium position. Find the force constant required for the spring.
A 2.8 kg block slides along a frictionless horizontal with a speed of 5.5 m/s. After sliding a distance of 8m, the block makes a smooth transition to a frictionless ramp inclined at an angle of 43 degrees to the horizontal. The acceleration of gravit..
A 21 g bullet travelling at 255 m/s is fired into a 0.452 kg wooden block anchored to a 100 N/m spring. How far is spring compressed to the nearest thousandth of a meter.

What is the tangential acceleration of a bug on the rim of a 13.0-in.-diameter disk if the disk accelerates uniformly from rest to the angular speed of 76.0 rev/min in 3.50 s.
Determine the resolution limit set by diffraction . what average force do you need to apply to stop the sled? Utilize the concepts of impulse and momentum.
With the battery disconnected the compass needle points to the right, in the plane of the coil. The apparatus is located near equator, where the Earth's magnetic field B Earth is horizontal, with a magnitude of 4×10-5 tesla. (Presume that B Earth ..
Approximately how many atoms make up our planet? For simplicity, suppose the average atomic mass of the atoms is 14 . Avogadro's number gives the number of atoms in a mole.
A uniform density cube of mass m, side 2b, and center at C is placed on a fixed horizontal cylinder of radius r and center O in Earth's gravitational field. The cube is originally put so that C is centered above O, but it can roll from side to side w..
