Answer:
The acceleration of the box is 0.67 m/s²
Explanation:
Given that,
Mass of box = 30.0 kg
Horizontal force = 230 N
Friction force = 210 N
We need to calculate the acceleration of the box
Using balance equation


Where, F = horizontal force
=frictional force
m= mass of box
a = acceleration
Put the value into the formula


Hence, The acceleration of the box is 0.67 m/s²
The process of evaluating evidence to form an attitude should be called Cognitive evaluation.
Answer:
The answer is C 0.0
Explanation:
Because its sitting still on the ground.
Average velocity = (displacement) / (time)
Displacement = distance and direction between start and end points
Displacement = 25 km east
Average velocity = (25 km east) / (4 hours)
<em>Average velocity = 6.25 km/hr east</em>
