Question

Velocity of a Helicopter: A helicopter is 240 feet above its landing pad. Twenty seconds later, it lands. What was its velocity? What was its speed?

a) Velocity is 12 feet per second, Speed is 12 feet per second
b) Velocity is 20 feet per second, Speed is 12 feet per second
c) Velocity is 12 feet per second, Speed is 20 feet per second
d) Velocity is 20 feet per second, Speed is 20 feet per second

Answer 1

The velocity of the helicopter is 12 feet per second and its speed is also 12 feet per second.

Step-by-step explanation:

The velocity of the helicopter can be calculated by dividing the change in height by the time taken. In this case, the helicopter is 240 feet above its landing pad and it takes 20 seconds to land. Therefore, the velocity is 240 feet divided by 20 seconds which equals 12 feet per second.

The speed of the helicopter is the magnitude of its velocity, so it is also 12 feet per second. Therefore, the correct answer is option a) Velocity is 12 feet per second, Speed is 12 feet per second.
