PART a)
By energy conservation we can say


divide whole equation by mass "m" and plug in all given data
![9.8(1.24) + \frac{1]{2}(1.7)^2 = 9.8(0) + \frac{1}{2}(v)^2](https://tex.z-dn.net/?f=9.8%281.24%29%20%2B%20%5Cfrac%7B1%5D%7B2%7D%281.7%29%5E2%20%20%3D%209.8%280%29%20%2B%20%5Cfrac%7B1%7D%7B2%7D%28v%29%5E2)

so gymnast will reach the floor with speed 5.21 m/s
PART b)
Now the gymnast bend her knees by 0.1 m and comes to rest
so here we will have



now the force on the gymnast will be


so during landing the force will be 6798.5 N
weathering refers to the actual breaking part of the rock or soil. deposition happens when the weathered and eroded material is deposited and finally comes to a stand still.
Answer:
Explanation:
From the given information:
Let the first weight be
= 80 kg
The weight of the buddy be
= 120 kg
The weight of Bubba be
= 60 kg
Also, since you and Budda are a distance of 4m to each other, then the length to which both meet buddy will be:

The length of the boat be
= 4 m
∴
We can find the center of mass of the system by using the formula:

Answer:
The smallest part of a millimeter that can be read with a digital caliper with a four digit display is 0.02mm. Thus, it has to be converted to centimetre. So, divide by 10, we then have 0.02/10= *0.002cm* not mm.
