Answer:
The frog takes 8 jumps to reach top of well
Explanation:
Given data
Frog at bottom=17 foot
Each time frog leaps 3 feet
Frog has not reached the top of the well, then the frog slides back 1 foot
To Find 
Total number of leaps the frog needed to escape from well
Solution
in 1 jump distance jumped=3+(-1)
                                            =2 feet
                                            =2×1 feet
The "-1" is because the frog goes back
Now After 2 jumps the distance jumped as:
                      Distance Jumped=2+2
                      Distance Jumped=2*2
                                                    =4 feet
Similarly after 7 jumps
                     Distance Jumped=2+2+......+2
                     Distance Jumped=2*7
                                                  =14 feet
Now after 8th jump the frog climbs but doesnot slide back as it is reached to the top of well.
So
               Distance Jumped=(Distance Jumped after 7 jumps)+3
                                            =14+3
                                            =17 feet
The frog takes 8 jumps to reach top of well                 
 
        
             
        
        
        
Answer:
<u>The magnitude of the friction force is 8197.60 N</u>
Explanation:
Using the definition of the centripetal force we have:

Where:
- m is the mass of the car
 - v is the speed 
 - R is the radius of the curvature
 
Now, the force acting in the motion is just the friction force, so we have:
 
 
 
<u>Therefore the magnitude of the friction force is 8197.60 N</u>
I hope it helps you!
