A 50.0g superball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.50ms, what is the magnitude of the average acceleration of the ball during this time interval? (note 1 ms= 10^-3 s.) Textbook answer to this problem is
Hi. Here's my problem:
"A tennis ball with a speed of 11.8 m/s is thrown perpendicularly at a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 8.51 m/s. If the ball is in contact with the wall for 0.00175 s, what is the average acceleration of the ball while it is in contact with the
-Compare and Contrast velocity or speed andacceleration.
-Consider the formulas, definitions, and units.
-Explain how Newton's Second Law of Motion APPLIES to a task you perform.
Describe Examples how you move an object or person with constant speed AND also with constant acceleration.
I constructed a fairly simple experiment related to curvlinear motion. The experiment involved a small metal ball that rolls off a table and lands on the floor. I used the edge of table as the Y direction.
I timed the trial run from the of the edge of the table and when the ball hits the floor. I know X (total of all time thr
Please see attached form. Show all work.
1. An object is thrown vertically upward with an initial velocity v0. At the highest point in the object's trajectory:
a. its velocity andacceleration are both zero.
b. its velocity andacceleration are both nonzero.
c. its velocity is zeor, and its acceleration is nonzero and dire
1. A particle oscillates between the points x = 40 mm and x = 160 mm with an acceleration a = k( 100 - x), where a and x are expressed in mm/ s^2 and mm, respectively, and k is a constant. The velocity of the particle is 18 mm/ s when x = 100 mm and is zero at both x = 40 mm and x = 160 mm. Determine (a) the value of k,( b) the
