An elastic conducting material is stretched into a circular loop of 9.55 cm radius. It is placed with its plane perpendicular to a uniform 0.955 T magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 75.8 cm/s. What emf is induced in volts in the loop at that instant

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.

A17,250 kg rocket is pushed with a thrust of 6,450,284 n. what is the acceleration of the rocket?

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
