Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. A motorist is about to enter the exit ramp of a highway. When it is 50m before reaching A (along the straight path), the motorist travels at 80km/h, decreasing at the rate of 0.5m/s2until it reaches B. After it reaches B, it travels at a constant speed. Determine the magnitude of the acceleration: just after A just before B just after B
A car is driving around a curve of radius 200 m, while increasing its rate at 0.80 m/s². At a certain instant, the magnitude of the total acceleration is measured to be 1.50 m/s². Compute for the speed of the car at that instant in kph.
A Car rounds a 100-m radius curve at a constant speed of 60 kph. Which of the following statements is/are TRUE considering its motion on the curve path? Select ALL possible answers. O The car has a tangential acceleration. The car has a normal acceleration directed towards the center of the curved path. O The car has a normal acceleration directed away from the center of the curved path. The car has no tangential acceleration. The velocity of the car changes at any instant. O none of these
The car travels around the portion of a circular track having a radius of r = 600 ft such that when it is at point A it has a velocity of 3 ft/s, which is increasing at the rate of 0.002t ft/s?, where t is in seconds. Determine the magnitudes of its velocity and acceleration when it has traveled two-thirds the way around the track. A
PROBLEM 2 The car is traveling at a speed of 75 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 15 ft/s? until it gets to point 8, after which its constant rate of decrease of speed is 3 ft/s2 as it rounds the interchange ramp. Determine the magnitude of the total car acceleration (a) just before it gets to B, (b) just after it passes B, and (c) at point C. Use 1 mile = 5280 ft. 200 A В 300
The gap between two consecutive automobiles (distance between the back of a vehicle and the front of the following vehicle) is 65 ft. At a certain time, the front vehicle is traveling at 45 mi/h, and the following vehicle at 35 mi/h. If both vehicles start accelerating at the same time, determine the gap between the two vehicles after 15 sec if the acceleration of the vehicles can be assumed to take the following forms: du/dt = 3.4 - 0.07u, (leading vehicle) du/dt = 3.3 - 0.065u, (following vehicle) where ut is the vehicle speed in ft /sec.
