SOLVE THE FOLLOWING ​

Answer 1

Heyy

We know that s = ut + 1/2at²

According to question, u = 0 [As it was in rest]; a = 3ms⁻² ; t = 8s

s = 0 x 8 + 1/2 x 3 x 8 x 8

s = 3 x 4 x 8

s = 96m

Hope that helps !!

Answer 2

Answer:-

Known Terms:-

u = Initial speed

v = Final speed

a = Acceleration

t = Time

s = Distance

Given:-

Initial speed of the motorboat, u = 0 km

Acceleration attain by the motorboat, a = 3 m/s

Time taken by the motorboat, t = 8 sec

To Find:-

Distance Travelled

Formula to be used:-

Motion 2nd equation that is $s=ut+\frac{1}{2}at^2$

Solution:-

Putting all values, we get

⇒ $s=ut+\frac{1}{2}at^2$

⇒ $s=8+\frac{1}{2}(3)(8)^2$

⇒ $s=96 \: m.$

Hence, the distance travelled by motorboat is 96 m.
