Hey everyone,
I'm doing a lab for engineering class, and I'm having a little trouble with a part of it. The lab was that we have a cannon on a table, with 3 launch settings (different lengths the spring is compressed). The table is 40" high. Also, we have a dixie cup 90" away from the table...
if a disk which is initially spinning with an angular velocity,w, radians per second is pushed with an initial linear velocity of v, what is the resultant motion? assume a kinetic friction of mu normal to the disk
i would love to see how this problem is solved. it seems real...
Simple Determination of Initial Velocity of a Projectile
It is possible to roughly determine the initial velocity of a projectile shot from a launcher like the one linked to below using a number of methods.

A 1.4 kg box slides 15m across the floor. The coefficient of kinetic friction between the box and the floor is 0.3. I found that friction force in slowing the box was -61.74J. Is this right?
What was the initial velocity of the box?
I worked this problem using Kf = Ki + Wnc and found...
Calc help please!
Can someone please help me how to do this problem using calculus? Thanks a lot.
A ball is dropped out of a window 19.6m above the ground. At the same time another ball is thrown straight down from a window 79.6m above the ground. If both balls reach the ground at the same...
Given: g = 9.8 m/s^2
A cannon sends a projectile towards a target a distance 1250m away. The initial velocity makes an angle 40 degrees with the horizontal. The target is hit.
What is the magnitude of the initial velocity?
How high is the highest point of the trajectory?
How long does...

A diver spings upward from a board that is three meters above the water. At the instant she contacts the water he speed is 8.90m/s and her body makes an angle of 75 degrees with respect to the horizontal surface of the water. Determine her initial velocity, both...
