In a vacuum a proton (charge =1.60 E-19 C, mass = 1.67×10-27 kg) is moving parallel to a uniform electric field that is directed along the +x axis. The proton starts with a velocity of v=2.50×104 m/s and accelerates in the same direction as the electric field, which has a value of 2.30×103 N/C. If the displacement of the proton is d=4.00 mm
A) Find the electrostatic force the proton experiences due to electric field
B) Determine the acceleration of the proton (Enter m/s2 - as m/s^2)
C) Find the velocity of the proton at the end of this displacement.
A 44.20 cm diameter disk rotates with a constant angular acceleration of 2.84 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at t..

Whats the coefficient of the kinetic friction of the tire. What is the acceleration of the car.
A proton is released from rest in a uniform electric field of magnitude 421 N/C. (a) Find the electric force on the proton. magnitude N direction (b) Find the acceleration of the proton. magnitude m/s2 direction (c) Find the distance it travels in..
How fast can this car round a second curve of radius 320m?
suppose that O&M costs (staff, maintenance, decommissioning, waste handling, training, refurbishment reserve and other charges) can be approximated by 12% of the debt charge and the fuel costs for the ACR's enriched fuel is about 3 percent of the deb..
A cylindrical container 1.1 tall contains mercury to a certain depth. The rest of the cylinder is filled with water.If the pressure at the bottom of cylinder is two atmospheres, what is the depth.
An 85.1 kg base runner begins his slide into second base while moving at a speed of 5.9 m/s. The coefficient of kinetic friction between his clothes and ground is 0.68. He slides so that he comes to rest just as he reaches the base.
A child of mass 24 kg sits 2.10m to the left of the center of a seesaw. The mass of the seesaw is 35 kg. How far to the right of the central pivot must a second child of mass 40 kg sit if the seesaw is to be perfectly balanced.
A small block of mass m = 1.5 kg slides, without friction, along the loop-the-loop track shown. the block starts from the point P a distance h = 54 m above the bottom of the loop of radius R = 17.0 m. What is the kinetic energy of the mass at the ..
