Question

Dina has a mass of 50 kilograms and is waiting at the top of a ski slope that’s 5.0 meters high. The maximum velocity she can reach when she skis to the bottom of the slope is meters/second.

Answer 1

Hello,

Your answer would be:

So Dina's maximum velocity on the bottom of the ski slope is v=9.9 m/s.

Answer 2

Answer:

speed will be approx 10 m/s

Explanation:

As per mechanical energy conservation we will say that if friction force is not present then total mechanical energy is always conserved

so here we will have

$U_i = KE_f$

now we will have

$mgH = \frac{1}{2}mv^2$

now we will plug in all values in it

$50(10)5 = \frac{1}{2}(50) v^2$

$v = \sqrt{2(10)(5)}$

$v = 10 m/s$

so here speed will be approx 10 m/s
