Two cars leave a stoplight, one 0.5128 s before the other. The second car accelerates with twice the acceleration of the first.
(a) How long after the first car begins to move does the second car pass it?
(b) What is the ratio of their speeds at that instant?
A 2.00-g charged particle is released from rest in a region that has a uniform electric field = (160 N/C), Determine the charge of the particle
Three point charges are arranged along the x axis. Charge q1= -4.70 nC is located at x= 0.200 m and charge q2 = 2.20 nC is at x = -0.340 m. A positive point charge q3 is located at the origin.
An 8.00 gram bullet is fired into a 250gm block that is initially at rest at the edge of a table of height 1.0 m. The bullet remains in the block, and after the impact the block lands 2.0 meters from the bottom of the table. Find out the initial s..
A constant magnetic field of magnitude 0.45 T is directed along the +y axis. The length of each rod is L = 1.3 m, and the speeds are the same, vA = vB = vC = 2.7 m/s. For each rod, find out the magnitude of the motional emf, and indicate which end..
