102.5 km/hr = 28.5 m/s
a = (28.5 - 0) / 10
a = 2.85 m/s²
Resultant force = forward force - friction
ma = F - μmg
F = ma + μmg
F = 905(2.85 + 0.795 x 9.81)
F = 9637.3 N
F = 9600 N
<h3>Answer</h3>
C
The object is at rest or is traveling at constant velocity.
<h3>Explanation</h3>
Acceleration is rate of change of velocity and velocity is a vector quantity which means that it is speed with direction.
If acceleration is zero it means that velocity is constant.
Constant velocity may include zero velocity or "at rest"
and
Speed is zero or speed is constant and no change in direction
Answer:
A
