A car moving along a straight highway with a speed of 72kmh−1 is brought to a stop within the distance of 100m. What is the retardation of the car and how long does it take for the car to stop ? View Solution A car moving aling a straight highway with speed of 126 km h^(...
A car A is travelling on a straight level road with a uniform speed of 60 km/h. It is followed by another car B which in moving with a speed of 70 km/h. When
9 A car is moving at constant speed in a straight line with the engine providing a driving force equal to the resistive force F.When the engine is switched off, the car is brought to rest in a distance of 100 m by the resistive force.It may be assumed that F is constant during the...
(3)Find the average acceleration of the car (in miles per hour per hour) over the interval [0,0.4]. (4)What does the integral∫ _0^1v( t)dtsignify? Approximate this integral using the Midpoint Rule with five subintervals. (5)Approximate the acceleration at t=0.8. ...
