Q1. A 370-kg sailboat has an acceleration of 0.87 m/s2 at an angle of 64° north of east. Find the magnitude and direction of the net force that acts on the sailboat.

Q2. A small immersion heater is rated at 620. Assess how long it will take to heat the cup of soup (assume this is 250 of water) from 18 to 74.

Q3. An object travelling along a straight line changes its speed from 23.0cm/s to 55.0cm/s in 11.0 s. assuming that the object is accelerated uniformly, what is the acceleration throughout this period?
