Please help in solving. Please show step by step solution to understand.

Show ALL your work for each question. DO NOT compound calculations - marks will be lost Show all units and conversions. Use ONLY the formulas and conversion units given in this course for calculations. Provide final answers to 3 decimal places. Be sure to write legibly - if I cannot read it I will not mark it = mark of 0 Assignment is due at the BEGINING of next class - NO exceptions. You will also need formulas from the past 3 weeks for this assignment. 1. An emergency brake lever requires 70N of force to engage. If the driver does 10.5 J of work, how far does the lever travel? 12 Data List: 2. A 250kg engine is placed on a stand and pushed a distance of 5m with a force of 20N. Calculate the work done. /2 Data List:5. Calculate the mass of a 600hp vehicle that accelerates at 15 m/s over 0.80km in 0.7 minutes. /10 Data List:5000 SERIES 7. A vehicle that produces 8500N of force at the wheels enters a highway at 4:20pm with a velocity of 48 m/s. The vehicle travels at a constant velocity and exits the highway at 4:45pm. Generate a "data list" for each calculation a) How far did the vehicle travel? (2 marks) b) What is the mass of the vehicle? (4 marks) c) How much hp did the vehicle produce at the wheels? (6 marls) d) If the engine inputs 559,500 Watts of power into the transmission, what is the efficiency of the vehicle's drivetrain? (2 marks) /146. What is the efficiency of a chain and pulley system if a technician does 19.30 kJ of work while pulling on the chain, to lift a 200kg engine 4m above the ground? /6 Data List:3. Calculate the power of a 70kg person that runs up a flight of stairs with a vertical height of 5m. It takes the person 7s to complete the trip. /6 Data List: 4. A 950kg vehicle can accelerate at a rate of 8 m/s2. Calculate the vehicles horsepower, if we test the acceleration over 0.30km and record a time of 15s. 18 Data List
