mmkay, i tried that, and I also got .23. But .23/3 gave me .063... and the answer was still incorrect, am I dividing by the right number of time intervals?
Well, I know the initial velocity is right, its a two part problem and that was the answer to part A, as for the diagram it's multiple pictures of a single ball being launched in an arc shape. I need to find the time between each picture. I tried finding the time to reach the max height, and...
Homework Statement
In the photograph , suppose the cart that launches the ball is 13 cm high. The vertical distance from the lowest ball to the highest is about two cart heights or 26 cm.
Estimate the time interval between successive stroboscopic exposures.

The Attempt at a Solution
Y Component: 65m*cos(35) = 53.24m
Z Component: 65m*cos(55) = 37.28m
I think...
Homework Statement
A hot-air balloon has just lifted off and is rising at the constant rate of 2.3 m/s. Suddenly one of the passengers realizes she has left her camera on the ground. A friend picks it up and tosses it straight upward with an initial speed of 12 m/s. If the passenger is 2.5m...
