A Saturn V's mass at liftoff was 2.80 × 10⁶ kg, its fuel-burn rate was 1.40 × 10⁴ kg/s, and the exhaust velocity was 2.40 x 10³ m/s. Calculate its initial acceleration.

Strategy
This problem is a straightforward application of the expression for acceleration because is the unknown and all of the terms on the right side of the equation are given.
