Coefficient of kinetic friction </h3>
The coefficient of kinetic friction between the base runner and the ground is calculated as follows;
μ = a/g
where;
- a is acceleration
- g is gravity
v² = u² + 2as
a = (v² - u²)/(2s)
a = (8.451² - 2.322²)/(2 x 6.596)
a = 5 m/s²
μ = 5/9.8
μ = 0.51
Thus, the coefficient of kinetic friction between the baserunner and the ground is 0.51.

Initial momentum = 0.15 kg * (-5 m/s) = - 0.75 N*s
final momentum = 0.15 * ( 3 m/s) = 0.45 N*s
Change in momentum = final momentum - initial momentun =
= 0.45N*s - (- 0.75N*s) = 1.2 N*s
Answer: 1.2 N*s
Answer:
His average speed.
Explanation:
Average speed = Total distance travelled / total time .
In the given case odometer measures total distance travelled . Dividing it by time will give average speed .
Average velocity can not be the answer as it is measured by dividing displacement by time . Displacement here is zero because initial and final point are same . Instantaneous velocity is given by the speedometer . It keeps on changing all the time . It is actually speed at a particular point of time . It can not be average velocity or speed .
