Answer:
final velocity is 40 m/s
the distance travelled is 750m
Explanation:
the distance travelled is 750m
From v = u + at
v = 10 + 1 × 30
v = 10 + 30
v = 40 m/s
Therefore, final velocity is 40 m/s
Also From equation of motion:
v^2 = u^2 + 2as then
[tex]s = \frac{ {v}^{2} - {u}^{2} }{2a} = \frac{ {40}^{2} - {10}^{2} }{2 \times 1} [/tex]
[tex] = \frac{(40 - 10)(40 + 10)}{2} [/tex]
[tex] = \frac{30 \times 50}{2} = 15 \times 50[/tex]
= 750m
Therefore, the distance travelled is 750m
