Answer:
a)1.7 ms⁻¹
b)24.75 m
Explanation:
Acceleration (a) = Change of velocity / Time taken (t)
a = [final velocity(v)- initial velocity(u)] / t
a = (v-u)/t ⇒ v = u +at
v = 0.8 + 0.06×15 = 1.7 ms⁻¹
displacement(s) = [initial velocity(u) + final velocity(v)]/2×t
[tex]s = \frac{u+v}{2} t[/tex]
[tex]s = \frac{0.8+1.7}{2} 15[/tex] ⇒ 24.75 m
