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…
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) A large rotating cylinder uniformly increases in angular speed from rest to 0.180 rev/s in 35.0 s. What is its angular acceleration in radians per second per second? ?rad/s2 (b) The same cylinder again starts from rest and accelerates uniformly in the same time interval, but now the angular acceleration is double that found in part (a). What is true about the final angular speed? It is double the value given in part (a). It is the same as the value given in part (a). It is half the value given in part (a). It is quadruple the value given in part (a).
1. A truck undergoes an acceleration of 0.25m/s2. If its wheels are 1.0 meter in a diameter, what is their angular acceleration? 2. A record is dropped on a turntable rotating at 33.5 rpm. The record slips briefly before reaching the same speed as the turntable. If the turntable rotates through 20 degrees while the record is slipping, find the record's angular acceleration.

A particular bicycle has wheels that are 66 cm in diameter. The radius of the crank armis 18 cm. At its lowest point, the pedal is 16 cm above the ground. A person is pedalingthe bicycle such that the crank arm rotates once every second.Questions:1. Write an equation that models the vertical position of the foot with respect to theground, starting from the lowest point, as the crank arm turns.2. What is the rate of change of the vertical position of the foot when it is at themidline? Explain your answer3. How fast, in kilometres per hour, is the bicycle moving?4. Determine an equation that would model the foot’s position when the cyclist istraveling 5 km/h. Compare this equation to your equation from question 1 andexplain any differences.5. Use calculus to explain why the rotation velocity of a point on the perimeter of awheel is the same as the velocity of the pedal. Use examples to support youranswer.
The MDF sheet shown in the figure below iscut by a laser pointer, which moves through the curved groove. Your distance in meters measured along the slot is given by s = 9t2– 2t, with t in seconds. The laser is at A at time t = 0.2 s and at B when t = 9.2 s. Determine to two decimal places of precision:a) the magnitude of the average acceleration between A and B;b) the average vector acceleration between A and B
An electric car is subjected to acceleration tests along a straight and level test track. The resulting v-t data are closely modeled over the first 10 seconds by the function v = 24t - t2 +5t1/2, where t is the time in seconds and v is the velocity in feet per second. Determine the displacement s as a function of time over the interval 0 ≤ t ≤ 10 sec and specify its value at the indicated times.
Q1. A driver enters a curved car at 72 km/h, slows down, causing the speed to drop at a steady rate of 4.5 km/h every second. If the radius of curvature is 16.7 m. Find the acceleration of the car after 4 seconds from the driver starting to slow down.
Dr. Wang was doing donuts (i.e. driving in a circle) in his car over the weekend and used his iPhone to measure the acceleration he experienced (this is a true story). The plot below shows the lateral acceleration recorded by his iPhone. Knowing that he was maintaining a constant speed and that the radius of his donuts was 10 meters, determine how fast he was driving and approximately how many donuts (laps) did he completed in the 6 seconds shown?
