Question

A spy is running across the bridge of an aircraft carrier. The spy is moving with a velocity of - 4 m/s relative to the carrier. However, the aircraft carrier is moving with a velocity of 12 m/s. There is a person standing stationary on a beach watching the event. What will be the velocity of the spy according to the person on the beach? 8 m/s 6 m/s -4 m/s -7 m/s

Answer 1

The correct option is A

Step-by-step explanation:

From the question we are told that

The velocity of the spy relative to the carrier is
`v_s = -4 \ m/s`

The velocity of the aircraft carrier is
`v_a = 12 \ m/s`

Generally the velocity of the spy according to the person standing stationary on the beach is mathematically represented as

`v = v_s + v_a`

`v = -4 + 12`

`v = 8 \ m/s`
