A parcel cart moves along a straight track. Its velocity decreases uniformly during a braking test.
| Time since braking began in s\mathrm{s}s | Velocity in m/s\mathrm{m/s}m/s |
|---|---|
| 0 | 2.5 |
| 4.0 | 0.5 |
Calculate the displacement of the cart during the braking test.
Calculate the velocity of the cart 1.0 s after braking began.
