Answer:
<h3>The answer is 2 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

where
f is the force
m is the mass
From the question
f = 20 N
m = 10 kg
We have

We have the final answer as
<h3>2 m/s²</h3>

Answer: it is due to friction.
Explanation: if you were to push an object that is at rest, there is static friction that you would first need to overcome. An example would be pushing a car as it is in neutral. Pushing it takes more force and work to overcome that friction.
But once it overcomes static, it will then turn to kinetic friction. Once the car starts to move, you notice that it is easier to push. This is due to the fact that kinetic friction would equal normal force times the constant while the static friction is greater than or equal to the normal force times the constant.

Explanation:
Speed is distance over time.
500 km / 2 hr = 250 km/hr
Velocity is speed and direction.
250 km/hr north
1,119,000 basically 746 times 150 then multiply that answer by 10
Answer:Downward
Explanation:
As elevator is moving upward but is decelerating to stop at top
Suppose mg is the weight of man
N is the normal reaction
a is the acceleration

here upward direction is positive while downward direction is negative
Therefore net force is in downward direction
