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 person of mass 80 kg stands at the center of a rotating merry-go-round platform of radius 3.5 m and moment of inertia 920 kg cdot m^2. The platform rotates without friction with angular velocity 0.85 rad/s. The person walks radially to the edge ..
