Problem: A particle is moving along a straight line such that its position is given by s=(4t−t2)fts=(4t−t2)ft, where tt is in seconds. Question: Determine the average velocity of the particle during this time interval. Express your answer to three significant figures and include the appropriate units.
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…

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
Applying principles of dynamics, with step by step solutions pls (i give 5 stars) A freighter is moving at a speed of 8 nautical miles per hour. The engines then had to be suddenly stopped. If it takes 10 minutes for the freighter to reduce its speed to 3 knots, determine the distance moved by the ship and its speed at the end of this interval. The deceleration of the ship is propor-tional to the square of its speed such that a = -kV^2.
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?
