Answer:

State the givens and the unknown. Use the first equation of motion — the one where velocity is a function of time.

v0 = 25 m/s

a = −2.0 m/s2

∆t = 3.0 s

v = ?

v = v0 + at

v = (25 m/s) + (−2.0 m/s2)(3.0 s)

v = 19 m/s

Restate the givens and the unknown from the previous part, since they're all still valid. Use the second equation of motion — the one where displacement is a function of time.

v0 = 25 m/s

a = −2.0 m/s2

∆t = 3.0 s

∆s = ?

∆s = v0t + ½at2

∆s = (25 m/s)(3.0 s) + ½(−2.0 m/s2)(3.0 s)2

∆s = 66 m
