When a light ray is reflected in many directions from a surface, the reflection is said to be
a. partial
b. complete
c. specular
d. diffuse

answer

c, on a nylon carpet in a dry area. give me brainliest

explanation:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
