... • With no external horizontal forces, it follows from the impulse-momentum principle that the horizontal component of momentum is conserved. This relation can be solved for the velocity of B at its maximum elevation. • The conservation of energy principle can be applied to relate the initial kinetic ...

... A ‘smart’ student decides to save energy by connecting his exercise treadmill to his laptop battery. If it takes 70 J to move the belt on the treadmill by 1 meter and 50% of the generated energy is stored in the battery, how ‘far’ must the student run to use his 100 W laptop for free for 2 hours? ...

... (a) Calculate the impulse experienced when a 70. Kg person lands on firm ground after jumping from a height of 3.0 m. (b) Estimate the average force exerted on the person’s feet by the ground if the landing is stiff-legged, and again (c) with bent legs. With stiff legs, assume the body moves 1.0 cm ...

... Recently, we reported near 100% efficient EIT in a Pr3+ doped Y2SiO5 (Pr:YSO) crystal14 wherein transparency of probe field was demonstrated at line center in an optically thick sample. At low temperatures, this "dark resonance" has a width on the order of 10's kHz. This potentially makes it suitabl ...
