Answer:

Explanation:

s = s₀ + v₀t + ½at²

50 = 0 + 0(4) + ½a(4²)

50 = 8a

a = 50/8 = 6.25 m/s²

a car has a velocity of 10ms-1. it accelerates at 0.2 ms-2 for half minute find the total distance travelled and final velocity

Readme [11.4K]

Answer:

Final velocity = 16 m/s

Total distane travelled = 390 m

Explanation:

We can use equation of motion to solve this:

$v = u + at \\ v = 10 + 0.2(30) \\ v = 16 {ms}^{ - 1}$

$s = ut + \frac{1}{2} a {t}^{2} \\ s = 10(30) + \frac{1}{2} (0.2) {(30)}^{2} \\ s = 390m$
