Question
help please
A cannon at the top of a cliff always fires cannonballs with an initial velocity of 60.0 m/s. Two identical cannonballs arc fired at different initial angles (ignoring air resistance): Cannonball A is fired at 20.0 degree above the horizontal, and takes 7.56 s to land. Cannonball B is fired at 20.0 degree below the horizontal, and takes 3.37 s to land. Decompose BOTH cannonballs' initial velocities, VA0 and VB0, into their x- and y-components. Finish by writing out both VA0 and VB0 in component notation. Show your work clearly, and explain any shortcuts. Using the information for either cannonball A or B (you don't need both), find the height H of the cliff. Show your work.
Explanation / Answer
a)
VAox=60
