Two identical charges, each -8.00 E-5 C, are separated by a distance of 20.0 cm (100 cm = 1 m). What is the force of repulsion? Coulomb's constant is 9.00 E9 N*m2/C2
Remember to identify all data (givens and unknowns), list equations used, show all your work, and include units and the proper number of significant digits to receive full credit.
A 12.0 g bullet is fired horizontally into a 106 g wooden block that is at first at rest on a frictionless horizontal surface and connected to a spring having spring constant 143 N/m.
A baseball player hits a baseball (m=.14kg) the ball is initiallytraveling horizontally with a speed of 40 m/s. The batter hits afly ball with speed vf=55m/s. What is the magnitude anddirection of the impulse imparted to the ball?
Over the years there has been a dramatic increase in the flight speed (U), altitude (h), weight (w), and wing loading (/A weight divided by wing area) of aircraft. Use the data given in the table below to determine the lift coefficient for each of..
let ?1 and ?2 be the ground state and first excited state wave functions for a particle in a deep potential well of width L. calculate the uncertainty in momentum
A toy cannon uses a spring to project a 5.80 g projectile. The spring is originally compressed with 8.00 cm and has a force constant of 15.54 N/m. When the spring is released, the projectile slides 15.0cm during the barrel of the cannon where the bar..
