question 41

Short Answer

A spacecraft is measured by a scientist on the ground to have a length of 81 m as it flies overhead with a speed $2.4 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s }$ The spacecraft then lands and its length is again measured by the scientist at rest on the ground.What result does he now get for the length of the spacecraft? (c = 3.0 × 10⁸ m/s)
