Answer #1

as coin is tossed upward but you will be moved forward.

hence coin will land behind you.

(B) x = t^2 - 3t + 2

x(2) = 2^2 - 3(2) + 2 = 0

x(3) = 2 m/s

<v> = x(3) - x(2) / (3 - 2)

= 2 m/s

    A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...
