(a) On a warm, dry day, you may get an electric shock when you slide out of a car seat and then touch the body work of the car. Explain why this happens,
(b) If you hold on to the body work of the car as you slideout, you do not get a shock. Explain
why not.
(C) Why are you more likely to notice this on a warm, dry day? Plz answer

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
