On level ground a shell is fired with an initial velocity of
at 60.0° above the horizontal and feels no appreciable air
resistance. (a) find the horizontal and vertical components of the
shell’s initial velocity. (b) how long does it take the shell to reach
its highest point? (c) find its maximum height above the ground.
(d) how far from its firing point does the shell land? (e) at its
highest point, find the horizontal and vertical components of its
acceleration and velocity.

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a

At what time would the magnitude of the velocity reach 36.00 km/hr
