7. A 1.50 x 103 kg car accelerates uniformly from rest to 10.0 m/s in 3.00 s. a. What is the work done on the car in this time interval?

b. What is the power delivered by the engine in this time interval?

Work done = force*distance = mass*acceleration*distance

acceleration = 10/3 = 3.33 m/s^2

distance = ((0+10)/2)*3 = 15m

work done = 1500*3.33*15 = 74900 J

Power = workdone/time = 74900/3 = 25000 W

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
