Two 6.0 kg objects head toward each other. Object A moves with a velocity of +7.0 m/s and Object B travels with a velocity of -5.0 m/s.
What are their resulting velocities if the collision is perfectly elastic?
What are their resulting velocities if the collision is perfectly inelastic?
Light from a laser beam with a wavelength of 600 nm passes through a narrow single slit and observed on a screen 1.5 m behind the slit. The first minimum of the diffraction pattern is 1.5 cm from the central maximum.
A square loop 15.0cm on a side has a resistance of 8.05? . It is initially in a 0.395T magnetic field, Calculate the electric energy dissipated in this process
You pull downward with a force of 32 N} on a rope that passes over a disk-shaped pulley of mass 1.2 kg and radius 0.07 5m. Find the linear acceleration of the 0.61 kg mass.
Illustrate the force vectors with their tails at the origin of coordinate system. The orientation of your vectors will be graded. The exact lengths of your vectors will not be graded but relative length of one to the other will be graded.
