Two laboratory trolleys move along the same horizontal track. A braking device exerts the same constant force opposite to the motion of each trolley until it stops.
| trolley | mass in kg\mathrm{kg}kg | initial speed in m/s\mathrm{m/s}m/s | distance moved while braking in m\mathrm{m}m |
|---|---|---|---|
| A | 0.80 | 1.5 | 0.45 |
| B | 1.20 | 2.0 | to be calculated |
Calculate the distance moved by trolley B while the braking force acts.
