A rocket sled is tested at "5 g" (5 times the acceleration due to gravity). If the sled starts from rest at position do= 0.00, how long does it take to travel 441 meters?
t = _____ s
18.0
4.24
9.00
3.00

Use this kinematics equation, solve it for t (noting that initial velocity, v₀ = 0), and then plug in known values:
Δx = v₀t + 0.5at²
t = √[2Δx/a]
= √[2(441m) / 5(9.81m/s²)]
= 4.24s
Hope this helps.
