Answer:
<em>The cyclist takes 10 seconds to accelerate to 12 m/s.</em>
Explanation:
<u>Constant Acceleration Motion</u>
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

Solving for t:

The cyclist starts from rest (vo=0) and moves at vf=12 m/s with an acceleration
.
Calculate the time:



The cyclist takes 10 seconds to accelerate to 12 m/s.
Answer:
The shear modulus of the polymer is 5 MPa
Solution:
As per the question:
displacement of the top plate, d = 2 mm = 0.002 m
Horizontal Force, P = 2 kN = 2000 N
Width of the block, w = 100 mm = 0.1 m
By small angle analysis:
Angle, 
Now,
Stress,
=
