A missile is fired from a jet flying horizontally at Mach 2 (2200 ft/s). The missile has a horizontal acceleration of 1000 ft/s2. Calculate its horizontal velocity at 10.0 seconds after it is fired. (Assume constant acceleration of the missile throughout its flight.)

12,200 ft/s
10,000 ft/s
2300 ft/s
7800 ft/s

Question

A missile is fired from a jet flying horizontally at Mach 2 (2200 ft/s). The missile has a horizontal acceleration of 1000 ft/s2. Calculate its horizontal velocity at 10.0 seconds after it is fired. (Assume constant acceleration of the missile throughout its flight.)

10,000 ft/s
2300 ft/s
7800 ft/s

Vocaloid · Answer

vf = v0 + at
you are given v0 (initial velocity), acceleration (1000 ft/s2), and time (10s)
solve for vf
