While driving a car at 90 km/h, how far do you move while your eyes shut for 0.50 s during a hard sneeze?
Solution:
The speed (v), the car travels at is 90 km/h. Let us convert this to m/s.
v = (90\frac{km}{h})(1000 \frac{m}{km})( \frac{1}{3600 \frac{s}{h}})
v= 25m/s
The distance traveled is equal to the speed multiplied by the time. Therefore, in .50 s, the car will travel, d = vt = (25m/s)(0.50s) = 12.5 m.
