Question

A jet plane starts from rest with an acceleration of 3m/s^2 and makes a run for 35s before taking off. What is the minimum length of the runway?

(a) 105 m

(b) 1837.5 m

(c) 2451 m

(d) 1204 m

The question was asked in my homework.

This interesting question is from Motion and Mechanics topic in chapter Advanced Engineering Materials of Engineering Physics II

Answer 1

The correct choice is (b) 1837.5 m

The best I can explain: Minimum length of the driveway is given by s = ut + 1/2 at^2 = 0 + 1/2 × 3 × 35 × 35 = 1837.5 m.
