2. A Hyundai Santa Fe travels a 1.30km levelled road fromBonifacio roundabout to City Lights Hotel in a minimum time of45.60seconds. Given that the car accelerates and deceleratesat 2.53 m/s², which starts from rest at the roundabout andcoming to a stop at the Hotel, determine the maximum speed (inkph) and the time (in seconds) it travel at this speed. Assumetime for acceleration and deceleration are equal.

Speed is the time rate at that a car is moving along a direction, while velocity is the rate and…

3.2 m A vehicle moves in a straight line such that for a short time its velocity v = (0.4t + 0.6vt) m/s where t is in second (ift=D0, s=0).Determine it acceleration(a) when t=4sec?
An automobile is traveling on a curve having a radius of 800 ft. If the acceleration of the automobile is 6 ft/s², determine the constant speed at which the automobile is traveling.
Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A sees and reacts very unwisely to the police car P. Car A is traveling at VÅ = 129 km/h as it passes P, but over the next 4.9 seconds, the car uniformly accelerates to 149 km/h, after which that speed is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.4 m/s² until a speed of 177 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. A Answer: s= VA P m

While a car is moving with a speed 108 k on a straight road the driver sees a truck which enters the road 75m ahead. The driver applies full brake 0.5s after s/he observes the truck, however the car hits the truck with a speed of 50 k. Then what would be the maximum initial speed of car in when the driver observes the truck in order that the car does not hit the truck with all other conditions are the same?
A car is traveling around a circular track of 660-ft radius. If the magnitude of its total acceleration is 6.2 ft/sec² at the instant when its speed is 32 mi/hr, determine the rate at at which the car is changing its speed. Answer: at = ± ft/sec²
