Answer:
Explanation:
Given
velocity at A is 
For 
velocity is increasing at 
Tangential acceleration is given by





at 


thus 
Velocity in terms of Displacement is given by



When car has traveled
th of distance i.e.




on solving we get 
Thus velocity at 

(b)Acceleration when car has traveled three-fourth the way of track
normal acceleration 

Tangential acceleration 

Net acceleration 

Answer:
YES
Explanation:
values other than five will work
Answer:
Shearing strain will be 0.1039 radian
Explanation:
We have given change in length 
Length of the pad L = 1.15 inch
We have to find the shearing strain
Shearing strain is given by

Shearing strain is always in radian so we have to change angle in radian
So
