Question

A car moving in the positive direction with an initial velocity of 26 m/s slows down at a constant rate of -3 m/s2. What is its velocity after 7 seconds of deceleration? Round the final answer to the nearest whole number.

Answer 1

The answer is 5 m/s
$- 3 = \frac{x - 26}{ 7} \\ x = \frac{7 \times( - 3)}{1} + 26 = - 21 + 26 \\ = 5$




good luck
