Question

At which velocity is a Space Capsule moving faster -100 miles per hour or 80 miles per hour

Answer 1

117.3 because it’s how fast and how long it’s taking the velocity

Answer 2

117.3 feet per second.

Explanation:

Velocity is the speed of an object in a definite direction. In mechanics, velocity is a vector quantity. It requires magnitude and direction to make any sense. Velocities are expressed per unit time.

The SI unit of time is the second.

Now, suppose we need the velocity in feet per second. A simple calculation will help:

feet per second = miles per hour × 1.466667 [ in other words, one mile per hour equals 1.466667 feet per second]

For a space capsule moving at 80 miles per hour, the velocity is given by

= 80 × 1.466667

= 117. 3 ft/s [feet per second]
