The material point is moving. with an acceleration of 0.3 m / s ^ 2. The initial speed is 6 m / s. Point speed will increase by 70% in?

First, we find the final speed: 6 + 6 * 0.7 = 10.2 (m / s)
Find the time from the formula: u = u (0) + at
We have: 10.2 = 6 + 0.3 * t, hence t = (10.2-6) / 0.3 = 14 s
