when evaluating the speed of an olympic sprinter we only need to know the length of the race and the elapsed time because speed is ________
scalar calculated as distance divided by time
a vector calculated as displacement divided by time
a scalar calculated as the time divided by the
the elapsed time
The correct answer is: a scalar calculated as distance divided by time.
a scalar calculated as distance divided by time
When evaluating the speed of an Olympic sprinter, we only need to know the length of the race and the elapsed time because speed is a scalar quantity calculated as distance divided by time. To find the speed, we divide the distance covered by the athlete (which is equal to the length of the race) by the time it took to cover that distance (the elapsed time). This gives us a scalar value representing how fast the sprinter was running without considering any direction or displacement.
