The correct answer is letter C. The angle of incidence is equal to 55 degrees. This is because Specular Reflection refers to mirror-like reflection of light or other kinds of waves from a surface. This phenomenon is where light from a single incoming direction is also reflection in a single-outgoing direction.
The answer is B. Unbalanced force

Answer:
The force is
Explanation:
Given that,
Mass of car = 64 kg
Suppose, a 1400-kg car that stops from 34 km/h on a distance of 1.7 cm.
We need to calculate the acceleration
Using formula of acceleration
Where, v = final velocity
u = initial velocity
a = acceleration
s = distance
Put the value into the formula
We need to calculate the force
Using formula of force
Negative sign shows the direction of the force is in the direction opposite to the initial velocity.
Hence, The force is
