Question

A comet traveling through space has a speed of 132 m/s. It undergoes an acceleration of 24.7 m/s^2 for a time of 45 seconds. What is the comet's final speed?

A) 220.3 m/s
B) 1320.5 m/s
C) 1110.5 m/s
D) 1327.5 m/s

Answer 1

To find the comet's final speed, use the equation Final speed = Initial speed + (Acceleration × Time). Plugging in the given values, the comet's final speed is 1243.5 m/s.

Step-by-step explanation:

To find the comet's final speed, we can use the equation:

Final speed = Initial speed + (Acceleration × Time)

Plugging in the given values, we get:

Initial speed = 132 m/s

Acceleration = 24.7 m/s^2

Time = 45 seconds

Final speed = 132 m/s + (24.7 m/s^2 × 45 seconds)

Final speed = 132 m/s + 1111.5 m/s

Final speed = 1243.5 m/s

Therefore, the comet's final speed is 1243.5 m/s.
