t = d/v = 510:340 = 1,5 secunde
1,4 secunde, deci
t2 = 1,5 - 1,4 = 0,1 secunde
v2 = distanta/timp = 510 metri / 0,1secunde
= <span>5100 metri / secunda</span>

Answer:
a. 1,188 N
b. 1.836
Explanation:
The computation is shown below:
a. For horizontal force, first we need to find out the circular path radius which is shown below:
As we know that


= 8m
Now the horizontal force is

where,
m = 66 kg
v = 12 m/s
and r = 8 m
Now placing these values to the above formula
So, the horizontal force is

= 1,188 N
b. Now the ratio of force to the weight of skater is

= 1.836
