A Russian MiG-25, nicknamed the “Foxbat” flies at 3395 km/h. a) Convert the Foxbat’s speed to m/s. b) A sneeze takes 0.50 s. Find the distance in meters the Foxbat flies in the time it takes you to sneeze. c) Find the Foxbat’s average acceleration if it takes 12.0 s to reach this speed from rest.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
