A vehicle manufacturer is considering an engine for a new sedan (CD = 0.41, Af = 1.95 m2).The car is being designed to achieve a top speed of 75 kph on a paved surface at sea level(p = 1.225 kg/m³). The car currently weighs 1100 kg, but the designers initially selected anunderpowered engine because they did not account for aerodynamic and rollingresistances. What they did not know is that the test is done on a downhill with a grade of%3D3%. If 1.2 kg of additional vehicle weight is added for each unit of horsepower needed toovercome the neglected resistance, what will be the additional horsepower of the car if itis to achieve the 75 kph top speed?9.962O 8.1754.446None of theseO 7.3546.7428.511

A car of mass 1.2 tonnes is traveling along a straight horizontal Road at a speed of 20 m/s when it breaks sharply then skids. Friction brings the car to rest. If the coefficient of friction between the tyres and road is 0.8, calculate the deceleration and the distance travelled by the car before ut comes to rest.
You are coasting on your 10-kg bicycle at 15 m/s and a 8.0-g bug splatters on your helmet. The bug was initially moving at 4.0 m/s in the same direction as you. If your mass is 70 kg, (a) what is the initial momentum of you plus your bicycle? (b) What is the initial momentum of the bug? (c)What is your change in velocity due to the collision with the bug? (d) What would the change in velocity have been if the bug were traveling in the opposite direction?
A 12.52 kN car has a 2.75 m wheelbase, with its center of gravity located 60 cm from the pavement and 115.0 cm behind the front axle. 4 people weighing on average 75 kg loaded the vehicle, shifting the center of gravity 12.0 cm nearer to the rear axle. What is the maximum tractive effort (N) that can be developed if the car is a front wheel drive? Use coefficient of road adhesion = 0.55 .
Rear Raised Standard 0.6 m 0.4 m 1.3 m 1.6 m 1.3 m 1.6 m Car image from YouTube.com Newton's Laws (Rigid Bodies): In an attempt to make her car accelerate faster, a drag racer has raised the rear of her car to increase the centre of gravity by 0.2 m. The shift in the horizontal location of the centre of gravity is negligible. The car has a mass of 1600 kg and the coefficient of friction is 0.3. The car is rear wheel drive. The front wheels roll freely. Neglect the mass of the wheels. Neglect the suspension deflection. Assume the front wheels stay on the ground. What is the change in maximum acceleration as a percentage taking the unraised car as the reference?
A motorcycle starts its motion from an initial speed of 10 km/h and accelerates to100 km/hr in 10 sec. Estimate the motorcycle acceleration, average speed and its distance traveled.
A light train made up of two cars connected by a coupling is traveling at 80 km/h when the brakes are applied to both cars. 80 KPH A B Knowing that car A has a mass of 20,000 kilograms and car B a mass of 25,000 kilograms, and that the braking force is 20 kN on each car, determine: (a) the distance traveled by the train before it comes to a stop(in meters), (b) the force in the coupling between the cars while the car is slowing down(in kN)
Problem 1. In deriving braking distance, we assume a constant acceleration/deceleration rate, a. In fact, AASHTO assumes constant acceleration a(t): = c (constant) in most of its design procedures. Although this is not entirely true, distances required for acceleration or deceleration can be realistic if appropriate values are chosen for the constant acceleration process. Linear acceleration a(t) = c₁t (t is time elapse and c₁ is jerk rate or rate of change) is a better approximation to the acceleration process. a) What is the practical stopping distance for a vehicle with initial speed 70 mph, if acceleration is described by a linear function of time using a(t) = -1.8t (t is time elapse in seconds). b) Use a constant acceleration rate to achieve the same stopping distance. What is this constant acceleration rate? Problem 2. A car hits a tree at an estimated speed of 25 mph on a 3 % upgrade. If skid marks of 120 ft are observed on dry pavement (coefficient of braking friction, fo…
