Mark and his Harley Sportster has a combined mass of 950kg. a) Ignoring road and air friction, how much work is involved in accelerating the motorcycle from 0 to 100km/hr.

b) Mark claims that his 95hp cycle can go from 0 to 100 km/hr in 3.5 seconds. Assuming 100% efficiency, is this possible? Show how much horsepower is required.

Expert Solution

In part a, work required is equal to the change in kinetic energy is just conservation of energy.

in part b we have calculated power required for accelerating from 0 to 100 km/h is 140.37 hp that is greater than bike's given capacity (95 hp). So it is not possible to accelerate from 0 to 100 km/h by his motorcycle. His claim is not correct.

If you have any doubt, feel free to ask in the comments.

Consider the following combined cycle. The mass flow rate of air is 73 kg/s. Air enters the compressor at state 1 with Patm =1 atm and Tamb = 20°C. The compressor has a pressure ratio of 7.5 and an efficiency ?c = 0.85. Air enters the combustor and is heated to a temperature TH = 1250°C. The turbine has an efficiency of ?t,1 = 0.87. The air leaving the turbine enters the steam boiler where it transfers heat to the...

A hot air balloon has a total mass of 750 kg (not including the air in the balloon) and holds a volume of 2.8 x 10^6 L of air. Assume the density of the air outside the balloon to be 1.2 kg/m^3 at a temperature of 20 degrees C and the air pressure is 101.3 kPa inside and outside the balloon. What is the minimum temperature for the air in the balloon to allow for the balloon to float? You...

A 1830-kg car experiences a combined force of air resistance and friction that has the same magnitude whether the car goes up or down a hill at 34.5 m/s. Going up a hill, the car's engine needs to produce 74.7 hp more power to sustain the constant velocity than it does going down the same hill. At what angle is the hill inclined above the horizontal?

Jason takes off from rest across level water on his jet-powered skis. The combined mass of Jason and his skis is 75 kg(the mass of the fuel is negligible). The skis have a thrust of 200N and a coefficient of kinetic friction on water of 0.10. Unfortunately, the skis run out of fuel after only 48s. What is Jason's top speed? A) 81 m/s B) 48 m/s C) 130 m/s D) 13 m/s

Write a Java program that will ask the user for his/her mark (numerical integer mark) and then convert this numerical mark into letter grades. The following is a guideline to the grading scale used. The numeric range within parenthesis maps to the preceding letter grade. If the user gave you a number greater than 100 or less than 0, you should print a message that the input is invalid. In this code, DO NOT USE && OPERATOR. You should use...

Suppose mark currently has $80,000 in wealth. Also suppose that there is a 1% chance that his house will be destroyed and cost $70,000 to repair (reducing your income to $10,000). Finally, suppose that his utility function is U = M , where M is income. What is the expected value of this situation? What is the expected utility? Would mark be willing to pay $500 to purchase an insurance policy that fully insures him against his loss? (Full insurance implies...
