Question
f a rock is thrown upward on the planet Mars with a velocity of 7 m/s, its height in meters t seconds later is given by y = 7t − 1.86t^2. (Round your answers to two decimal places.)
Estimate the instantaneous velocity when t = 1.
Estimate the instantaneous velocity when t = 1.
Answers
the velocity is dy/dt = 7 - 3.72t
plug in the value of t=1
plug in the value of t=1
