Answer = 1000N
F = ma
M = 500kg
a= 2 m/s/s
Solve for F
Answer:
If the earth lost its gravity we could not walk or live our normal ways
Answer:
option C
Explanation:
The correct answer is option C
There is no external force acting in the system hence the momentum will be conserved.
As the milk is leaking out of the tank mass of the tanker is decreasing.
When the mass of the container will decrease to conservation the momentum speed of the container will have to be increased.
So, the car carrying milk will speed up.
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
