A student races north across a football field The student crosses the football field (100 yards) in 10 seconds . What is the velocity of the student? a 1,000yards/sec north b 1yard/sec 10yards/second, north d 10yards/second west

The correct answer is c) $10 yards/second$, north.<br /><br />To calculate the velocity of the student, we need to divide the distance traveled by the time taken. In this case, the student crosses the football field (100 yards) in 10 seconds.<br /><br />Velocity = Distance / Time<br /><br />Velocity = 100 yards / 10 seconds<br /><br />Velocity = 10 yards/second<br /><br />Since the student is racing north across the football field, the direction of the velocity is north.<br /><br />Therefore, the velocity of the student is $10 yards/second$, north.
