well the formula to find speed is distance divided by time and you already have the time so all you need to know to find the average speed of the car is the total distance around the racetrake.
This is in the thermosphere which is at an altitude of 85-520km

Answer:
3. You are to determine the power rating of the motor in an elevator system. The elevator (with a full load) weights 1700 kg and is required to move upward 3 m/sec at constant speed. The lifting mechanism is 90% efficient (i.e., 10% of the power generated by the motor is wasted in the mechanism, e.g., for overcoming friction). What is the minimum output power rating in HP of the motor that meets the requirement?The Elevator (with A Full Load) Weights 2000 Kg And Is Required To Move Upward 3 M/sec At Constant Speed. The Lifting Mechanism Is 85% Efficient (i.e., 15% Of The Power Generated By The Motor Is Wasted In The Mechanism, E.g., For Overcoming Friction).
Explanation:
Explanation:
Using Cosine rule, we have 5² = 3² + 4² - 2(3)(4)(cosx).
=> cosx = 0, x = 90°.
