Answer (a) The work done by the engine is 12,000 J. (b) The power of the engine is 2.4 kW. Explanation: Given Data: Mass of car = 120 kg . Initial Speed = 18 km/hr. Final Speed = 54 km/hr. Time = 5 seconds. To Calculate: (a) The work done (b) Power . Calculations:. To solve the problem, we need to use the equations of motion and the AdvancedPhysics. Advanced Physics questions and answers. EXAMPLE 15.7 The 80-kg man can throw the 20-kg box horizontally at 4 m/s when standing on the ground. If instead he firmly stands in the 120-kg boat and throws the box, as shown in the photo determine how far the boat will move in three seconds. Neglect water resistance.
Supposeyou want to convert 120 kg into tonnes. Using the conversion formula above, you will get: 70 kg = 0.07 tonne: 80 kg = 0.08 tonne: 90 kg = 0.09 tonne: 100 kg = 0.1 tonne: 110 kg = 0.11 tonne: 120 kg = 0.12 tonne: Kg to tonnes conversion chart; 120 kg = 0.12 tonne: 130 kg = 0.13 tonne:
Thesimplest way to find how many pounds is 120 kg is to divide the kilogram value by 0.45359237. Using 120 kg as our example, it will look like 120 / 0.45359237. The result can be written down as follows: 120 kilograms is equal to 264.56 pounds. 120 kg is equal to 264.56 lb. 120 kg is equal to 264.56 lbs. Supposeyou want to convert 120 kg into ounces. Using the conversion formula above, you will get: 80 kg = 2820 ounces: 90 kg = 3170 ounces: 100 kg = 3530 ounces: 110 kg = 3880 ounces: 120 kg = 4230 ounces: Kg to ounces conversion chart; 120 kg = 4230 ounces: 130 kg = 4590 ounces: 140 kg =
Supposeyou want to convert 120 kg into oz. Using the conversion formula above, you will get: 80 kg = 2820 oz: 90 kg = 3170 oz: 100 kg = 3530 oz: 110 kg = 3880 oz: 120 kg = 4230 oz: Kg to oz conversion chart; 120 kg = 4230 oz: 130 kg = 4590 oz: 140 kg = 4940 oz: 150 kg = 5290 oz: 160 kg = 5640 oz:
Theanswer is 120 Kilograms is equal to 120 Kilo and that means we can also write it as 120 Kilograms = 120 Kilo. Feel free to use our online unit conversion calculator to convert the unit from Kilogram to Kilo. Just simply enter value 120 in 0fUKxW.
