A motorist is travelling at 72km/hr when he observes that a traffic light ahead of him turns red. The traffic light is timed to stay red for 22 seconds. If the motorists wishes to pass the light without stopping just as it turns green again, determine a) the required uniform deceleration of the car in m/s^2 b) the speed of the car in m/s as it passes the light.

A train travels between two stations 792 m apart in a minimum time of 41 seconds. If the train accelerates and decelerates at 2.4 m/s, starting from rest at the first station and coming to a stop at the second station, what is the maximum speed?
The position of a particle in millimeters is given by s = 70 - 17t + t2 where t is in seconds. Plot the s-t and v-t relationships for the first 10 seconds. Determine the net displacement Δs during that interval and the total distance D traveled. By inspection of the s-t relationship, what conclusion can you reach regarding the acceleration?
In a physics lab experiment, you release a small steelball at various heights above the ground and measure the ball’s speedjust before it strikes the ground. You plot your data on a graph that hasthe release height (in meters) on the vertical axis and the square of thefinal speed (in m2/s2) on the horizontal axis. In this graph your datapoints lie close to a straight line. (a) Using g = 9.80 m/s2 and ignoringthe effect of air resistance, what is the numerical value of the slope ofthis straight line? (Include the correct units.) The presence of air resistancereduces the magnitude of the downward acceleration, and the effectof air resistance increases as the speed of the object increases. Yourepeat the experiment, but this time with a tennis ball as the object beingdropped. Air resistance now has a noticeable effect on the data. (b) Isthe final speed for a given release height higher than, lower than, or thesame as when you ignored air resistance? (c) Is the graph of the releaseheight…

Specifically a dynamics problem: Two rockets start from rest at the same elevation. Rocket A accelerates vertically at 20 m/s2 for 12 s and then maintains a constant speed. Rocket B accelerates at 15 m/s2 until reaching a constant speed of 150 m/s.Construct the a-t, v-t, and s-t graphs for each rocket until t = 20 s. What is the distance between both rockets when t = 20 s?

The acceleration of a particle traveling along a straight line is a = ¼ s1/2 m/s2 ,where s is in meters. If v = 0 m/s and s = 1 m when t = 0 s, determine the particle’s velocity at s =2 m.NOTE #1 – A sketch of the scenario should be created by you to enhance your work.NOTE #2 – A particle is rather uninspiring, yet they are suitable in learning engineering scienceprinciples. You are welcome to spice up this problem by replacing the particle with a rigid bodyof interest to you. You are welcome to comment on your answer how replacing abstract conceptswith tangible examples influences your learning of dynamics topics
To be able to solve rectilinear problems with variable functions. A particle moving along a straight line is subjected to a deceleration a=(−2v3) m/s, where v is in m/s. If it has a velocity v=8 m/s and a position s=8 when t = 0, determine its velocity and position when t=3sec.
