Question

A car moving with an initial velocity of 25 meters per second north has constant acceleration of 3 meters per square second second. After 6 seconds, what will its velocity be?

Answer 1

To find the velocity of the car after 6 seconds, we can use the following equation of motion:

Final velocity (v) = Initial velocity (u) + (Acceleration (a) × Time (t))

Given: Initial velocity (u) = 25 meters per second north Acceleration (a) = 3 meters per square second Time (t) = 6 seconds

Plugging in these values into the equation:

Final velocity (v) = 25 meters per second north + (3 meters per square second × 6 seconds)

Final velocity (v) = 25 meters per second north + 18 meters per second north

Final velocity (v) = 43 meters per second north

Therefore, the velocity of the car after 6 seconds will be 43 meters per second north.
