Question

13) A ship drops out of warp speed near Earth at time t=0. To prevent hitting the Earth the ship must stop at a distance of at least 20,000 miles. The ships velocity with respect to time is v(t) = 1 √ t in miles per second. Find the maximum time in seconds that can elapse before the pilot has to slam on the brakes. Assume that the ship stops instantaneously.

Please use limits.

Answer 1

liven distance = 20,000 miles. V(t) = Vt miles per second distance = vt ds = udt s de for det. 3 > 20,000 TE 20,000 = - 3/2 Bc 20,000 = 7 23/ 30000 --> t-(30,000)? - 965.48438 seconds Scanned with CamScanner
