Part A What height does the projectile reach above the surface?
Part B An observation satellite orbits the planet at a height of 1000. What is the projectile's speed as it passes the satellite?
The particle then begins to move. Find out the speed of the alpha particle after it has moved through a potential difference of −3.45×10−3 V.
Two charged bodies exert a force of .145N on each other. If they are now moved so they are one fourth as far apart, what force is exerted.

An ideal spring has the spring constant k = 428 N/m. find the distance this spring must be stretched from its equilibrium position for 28 J of work to be done.
A 4 kg block is acted upon by three horizontal forces. 10n (to left) 5n(short arrow to right) 25n to right. what is the net horizontal force acting on the block? what is the horizontal acceleration of the block?
What is potential barrier for the molecule aggregation? Will the solution be stable at these conditions? Will it be stable at 100 mmol/L salt concentration?
The speed limit for both roads is 35 mi/h, and the driver of the northward-moving vehicle claims he was within the speed limit when the collision occurred.
A uniform horizontal wire with a linear mass density of 0.50 g/m carries a 1.8 A current. It is placed in a constant magnetic field with a strength of 4.00 x10-3 T. The field is horizontal and perpendicular to the wire. Neglect the magnetic field ..
