Question1

A 380 kg piano slides 3.9m down a 27 degree incline and is kept from accelerating by a man who is pushing back on it parallel to incline.

a) Find out force exerted by the man

b) find out work done by the man on the piano

Question2

The electric force between two electrons with a distance of 0.87 m between them is repulsive. Compute the electric force between these two electrons. The value of Coulomb constant 9 × 109 N · m2/C2 and elemental charge is 1.6 × 10−19 C.

Question3

A dragonfly is clocked at 2.0 m/s, North at one moment, and then 2.0 seconds later, dragonfly appears to be going just about 3.5 m/s, West. In that 2-second interval, what is an average acceleration of the dragonfly?
