Lesson: Applications on Motion with Uniform Acceleration Mathematics
In this lesson, we will learn how to solve problems involving motion of a particle with uniform acceleration through one or more sections of its path.
A man was driving his car in a straight line at 78 km/h when he pressed the brakes. If the car’s velocity decreased at a constant rate until it stopped completely over a period of 15 seconds, determine the stopping distance of the car.
A cyclist, moving in a straight line, accelerated over a distance of 35.5 m until his velocity reached 10.8 m/s. Given that this took 5 seconds, find the cyclist’s initial velocity.
A man, driving his car at 28 m/s, saw a child crossing the road in front of him. Given that the man’s response time was 0.6 seconds and that after he struck the brakes, the car decelerated uniformly at a rate of 10 m/s2 until it stopped, find the total stopping distance of the car.
