Answer:
3. Quadratic
Step-by-step explanation:
Penny is falling under gravity
acceleration due to gravity is constant
Velocity is the integral of acceleration, which is linear
Displacement is the integral of velocity, which is quadratic
Answer:
(3,2)
Step-by-step explanation:
3,2 is the answer...hope you can understand
- Initial velocity=u=0m/s
- Distance=s=150m
- Time=t=10s
- Acceleration=a
Using second equation of kinematics






Using newtons second law



Given:
The equation is

The incorrect solution steps are given.
To find:
The first error.
Solution:
We have,

Using distributive property, we get


The given step 1 is
, which is not correct.
Therefore, there is first error in step 1 because the distribution property is not used properly.
Hence, the correct option is D.
