Question

Determine the magnitude of the uniform velocity of an object that moves 800 m in 20 seconds going East.

A) 20 m/s
B) 40 m/s
C) 800 m/s
D) 1600 m/s

Answer 1

A) 20 m/s. The correct answer to the magnitude of the uniform velocity of an object moving 800 m in 20 seconds to the east is option

Step-by-step explanation:

The correct answer is option A) 20 m/s. To determine the magnitude of the uniform velocity, we use the formula for velocity which is the displacement divided by time. The total displacement is 800 meters east, and the total time taken is 20 seconds. Dividing the displacement by time, we get:

Velocity (v) = Displacement (Δx) / Time (t) = 800 m / 20 s = 40 m/s. This indicates that the object was moving with a uniform velocity of 40 m/s to the east.
