A projectile is shot horizontally at 59.9 m/s from the roof of a building 67.0 m tall. Determine the time necessary for the projectile to reach the ground below. Determine the distance from the base of the building that the projectile lands. Determine the horizontal and vertical components of the velocity just before the projectile reach the ground.

Acharge of 8.4x10^-4 c moves at an angle of 35 degrees to a magnetic field that has a field strength of 6.7x10^-3 t. if the magnetic force is 3.5 x10 ^-2 n, how fast is the charge moving?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

This is the substance(s) formed in a chemical reaction.
