Hello,

Your answer would be:

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

Answer:

speed will be approx 10 m/s

Step-by-step 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 = (1)/(2)mv^2

now we will plug in all values in it


50(10)5 = (1)/(2)(50) v^2


v = √(2(10)(5))


v = 10 m/s

so here speed will be approx 10 m/s
