Q1. A box of books weighing 397 N is shoved across the floor by a force of 543 N exerted downward at an angle of 37 degrees below the horizontal.

The acceleration of gravity is 9.81 m/s2.

If uk between the box and the floor is 0.55, how long does it take to move box 5.22 m, starting from rest.

Respond in units of s.

Q2. Assume we have an electron that is initially at rest in a uniform electric field with a magnitude of 732 V/m.

(i). If this electron moves a distance of 14 cm in this electric field, what is the potential difference between starting and ending points (identify which is larger)?

(ii). How fast is the electron moving at the position where it has moved the 14 cm above?
