The net force on a 1nC charge is 0. What is q?
There are 3 forces. q is 2cm in the y direction away from a charge of 1nC. Another charge of 2nC is 4cm below q and 3cm to the right. The final charge is 4cm below q and 3cm to the left. Using Coulomb's law, I found the force of the two...
A 1000 kg rocket is launched straight up. The rocket motor overcomes gravity to provide the rocket with a net constant acceleration upward for 16 seconds. The the motor shuts off. 4 seconds later the rocket's altitude is 5100 meters.
What is the rockets acceleration during the 1st 16...
A rocket is launched straight up with constant acceleration. 4 seconds after liftoff, a bolt falls off the side of the rocket. The bolt hits the ground 6.10s later. What was the rocket's acceleration?
rocket: xfinal = 1/2a^2 x 4s^2
bolt: vfinal = 0+ -9.9 m/s^2 * 2.1s
given this vfinal...
