A metallic wire of resistivity 2x 10-7Ω.m, has a section of 1 mm diameter & a resistance of 2.55 Ω. An electric current I passes through it. The electric energy consumed during 5 min. is 150 J. a. Calculate the length L of the wire.
b. Calculate the quantity of electricity that crosses the wire during 0.025 hours. (4pts)

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
