... FTmax = m(a + g) = (1200 kg)(0.0600 + 1)(9.80 m/s2) = 5.04104 N. The minimum tension will be exerted by the motor when the elevator is accelerating downward. We write ∑F = ma from the force diagram for the car: y-component: FTmin – mg = ma, or FTmin = m(a + g) = (1200 kg)(– 0.0600 + 1)(9.80 m/s2 ...

... If initially at rest, what force must Nils use to push Lars with an initial acceleration of 2.0 m/s2? Once moving, what force must Nils pull with to keep Lars moving at a constant velocity? After pulling Lars for while, Nils becomes tired so he lets go of the rope and jumps onto the sled. Assuming t ...

A frequency and wave vector within the band gap of the bulk system indicates that the mode is guided in the air region between the films. For each value of d / a, the group velocity of th ...

Electromegnatic Induction - GTU e
... An emf E is induced by moving wire at velocity v in constant B field. Note direction of I. From Lenz’s law, we see that a reverse field (out) is created. This field causes a leftward force on the wire that offers resistance to the motion. Use right-hand force rule to show this. ...
