- A car traveling at 30 m/sec has wheels with 75cm diameters. Find: angular speed of wheels, if the car stops in 5 sec, what is angular acceleration? how many revolutions do the wheels turn before stopping?A car starts from rest and accelerates to a speed of 90 km/h in 20 seconds. The acceleration during this period is constant. For the next 20 minutes the car moves with the constant speed of 90 km/h. At this time the driver of the car applies the brake and thecar decelerates to a full stop in 10 seconds. The variation of the speed of the car with time is shown in the accompanying diagram. Determine the total distance traveled by the car and the average speed of the car over this distance.A test car starts from rest on a horizontal circular track of 85-m radius and increases its speed at a uniform rate to reach 115 km/h in 18 seconds. Determine the magnitude a of the total acceleration of the car 14 seconds after the start. 85 m Answer: a = i m/s2
- Question: A motorcyclist travels along a straight road at a speed of (27 m/s). When the brakes are applied, the motorcycle decelerates at a rate of (-61 m/s²). Find the distance the motorcycle travels before it stops?A motorist is travelling on a curved section of highway of a radius 150 m at a speed of 4okph. The motorist suddenly applies the brake, causing the automobile to slow down at a constant rate. Knowing that after 10 seconds the speed of the car has been reduced to 20 kph. Find the normal component of acceleration 8 seconds after the brake has been applied in meters per square seconds. .You are driving a car along a straight road at 123 kph. Suddenly, you saw a cat crossing the road and you apply the brakes decelerating the car at a constant rate of -44.5 m/s2. If your reaction time is 1.50 seconds, what is the shortest stopping distance from the moment you see the cat? Illustrate the problem.
