A 2.0x10^-9 C point charge is located at x=3 cm and a -3.0x10^-9 C point charge is located at x=5 cm. Determine the force on the negatively charged object due to the positively charged object?
Two 3.5 kg bodies, A and B, collide. The velocities before the collision are A = (21 + 30) m/s and B = (-34 + 11) m/s. After the collision, ′A = (-4.5 + 16) m/s.
Determine the magnitude of the total initial momentum of the two-block system. Find , the magnitude of the final velocity of the two-block system. What is the change in the system's kinetic energy due to the collision?.
What is magnitude of the runners total displacement
A block of mass 2.7 kg being released from rest on a 1m frictionless plane, inclined at an angle of 40 degree. The block sided down the inclined and struck second block mass of 3.7 kg. If the two blocks stick together, with what speed would they move..
A 5 kg block slides down an inclined ramp at approximately constant velocity. The ramp angle is 23 degrees counter clockwise from the horizontal. What is the value of the force on the block due to friction between the block and the ramp? Show work..
