A car moving with an initial velocity of 25 m/s north has a constant acceleration of 3 m/s² south.After 6 seconds its velocity will be: A)7 m/s north B)7 m/s south C)43 m/s north D)20 m/s north E)20 m/s south

Question

The car's final velocity can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Here, acceleration is in the opposite direction to the initial velocity, so it's effectively a deceleration. The calculation is: 25 m/s - (3 m/s^2 * 6 s) = 25 m/s - 18 m/s = 7 m/s north.
