In this lab, an apple is released from rest and falls freely until it lands in a bowl. Watch the video here. We will be measuring y (the vertical position coordinate) as a function of time t. Notation: y0 is the value of y at t = 0; vy is the y-component of the velocity; vy0 is the value of vy at t = 0; ay is the y-component of the acceleration. The +y-direction is up. Assuming air resistance is negligible:

Which of these is the expected form of the equation for vy(t)?   (Click to select)

(a) vy(t) = v0yt + y0
(b) vy(t) = ayt2 + v0yt + y0
(c) vy(t) = ayt + v0y
(d) vy(t) = (1/2)ayt2 + v0yt + y0

Solutions

Expert Solution

From Newton's first equation of motion when applied along vertical direction, we have

vy=uy+ay×t, where vy is the final velocity along vertical direction, uy is the initial velocity along vertical direction, and ay is the the acceleration along vertical direction.

An apple drops from the tree and falls freely. The apple is originally at rest a height H0 above the ground. The ground is covered with a thick lawn, which is made of blades of grass of height h. When the apple enters the grass, it slows down at a constant rate so that its speed is 0 when it reaches ground level. A. Find the speed of the apple just before it enters the grass. B. Find the acceleration...

Ironman steps from the top of a tall building. He falls freely from rest to the ground a distance of h. He falls a distance of h/ 4 in the last interval of time of 1.0 s of his fall. Hint: First, compute the velocity when Ironman reaches the height equal to the distance fallen. This requires that you do the following: define origin as the bottom of the building. Then use x-x0 = -v0*(t-t0)-(1/2)g(t-t0)^2 where x=0 and x0= (distance...

1. A 58 g steel ball is released from rest and falls vertically onto a steel plate. The ball strikes the plate and is in contact with it for 0.5 ms. The ball rebounds elastically, and returns to its original height. The time interval for a round trip is 7 s. In this situation, the average force exerted on the ball during contact with the plate is closest to: 9300 N 3980 N 7960 N 5320 N 6620 N 2....
