as a pick up truck travels along a level stretch of road with constant speed, most of the power developed by the engine is used to compensate for the energy transformation due to friction force is exerted on the pick up truck by the air in the road. If the power developed by the engine is 2.23 hp, calculate the total friction force acting on the pick up truck (in N) when it is moving at speed of 29 m/s. 1 horsepower equal 746W

Expert Solution

If force is F and displacement of the object against the force is dx, then work done by the object is

if displacement is in the opposite direction of the force, then

Work done per unit time

then force

here

The constant drag force by the air is 57.36 N

3. An ambulance travels back and forth at a constant speed along a road of length L. At a certain moment of time, an accident occurs at a point uniformly distributed on the road. [That is, the distance of the point from one of the fixed ends of the road is uniformly distributed over (0, L).] Assuming that the ambulance’s location at the moment of the accident is also uniformly distributed, and assuming independence of the variables, compute (a) The...

A tourist is driving a car along a straight road at a constant speed of 22.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 2.50 m/s2 to overtake her. Assume that the officer maintains this acceleration. (a) Determine the time it takes the officer to reach the tourist (in s). 18 s (b) Find the speed of the officer as he overtakes the tourist (in m/s). 45 m/s...

A truck accelerates uniformly from rest to 19.5 m/s in 5.3 s along a level stretch of road. Determine the average power required to accelerate the truck for the following values of the weight (ignore friction). (a) 1.00x10^4 N (b) 1.20 x10^4 N

A speeding car is traveling along a straight road with a constant speed of 100 km/hour....

A speeding car is traveling along a straight road with a constant speed of 100 km/hour. It passes a police car. The officer starts 5.00 s after the speeder passes. The police car accelerates uniformly (i.e., at a constant acceleration) for 10.0 s, at the end of which its speed is 120 km/hour. After that, the police car moves with the constant speed of 120 km/hour till it reaches the speeding car. How far ahead of the police car is...

A) A car travels at a constant speed of 32.5 mi/h (14.5 m/s) on a level circular turn of radius 49.0 m, as shown in the bird's-eye view in figure a. What minimum coefficient of static friction, μs, between the tires and the roadway will allow the car to make the circular turn without sliding? B) At what maximum speed can a car negotiate a turn on a wet road with coefficient of static friction 0.215without sliding out of control?...

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 71 miles per hour, with a standard deviation of 4 miles per hour. Estimate the percent of vehicles whose speeds are between 63 miles per hour and 79 miles per hour. (Assume the data set has a bell-shaped distribution.) Approximately what % of vehicles travel between 63 miles per hour and 79 miles per hour.

Assume the speed of vehicles along an open stretch of a certain highway in Texas that is not heavily traveled has an approximately Normal distribution with a mean of 71 mph and a standard deviation of 3.125 mph. The current posted speed limit is 65 mph. What is the proportion of vehicles going above the current posted speed limit? What proportion of the vehicles would be going less than 50 mph? What proportion of the vehicles would be going between...
