Question

if a snowbile accelerate at the rate of -0.60m/s from its intial velocity of 3.0m/s. how long will it take to reach a complete stop?

Answer 1

Question

We have: $\nu_{1} = \nu_{0} + at$ .

We know that:

$$\begin{array}{l} v _ {0} = 3 \frac {m}{s} \\ a = - 0. 6 \frac {m}{s ^ {2}} \\ v _ {1} = 0 \frac {m}{s} \\ \end{array}$$

And we need to find $t$ .

So, we will have: $t = \frac{v_1 - v_0}{a} = \frac{0 - 3}{-0.6} = 5$ seconds.

Answer: 5 seconds.
