d. 35 m/s east

Let east be + Let west be –

v = vf – vO = 15 m/s - (-20 m/s) = 35 m/s east

Problems $400Answer

Back to Jeopardy

What is the average acceleration of a ball that is thrown vertically upward on Vulcan with an initial speed of 40.0 m/s if it takes 4.00 s to return?

Time up is 2.00 s Time down is 2.00 s

Using time up t = 2.00s

vf = 0 = vO + at a = -vO /t = -(40.0 m/s)/(2.00 s) = -20 m/s²

Local gravity on Vulcan is 20 m/s² down
