Answer:
3
Explanation:
During a crash 3 types of collisions can occur.
Answer:
-6
Explanation:
FRICTIONAL force=-300N,NORMAL REACTION,R=+50.0
Ú=F/R
=-300/+50.0
=-6
Answer:
The statements are missing!
Answer:
v = at + u
Explanation:
acceleration, a = constant
As we know that acceleration is the rate of change of velocity
integrate on both sides
v = at + u
Where, u is the integrating constant and here it is equal to the initial velocity
Now we know that the rate of change of displacement is called velocity
Integrate on both sides
where, xo is the integrating constant which is initial position of the particle.
The work done to push the refrigerator is 500 Nm.
Explanation:
Work done is the measure of force required to move any object from one point to another. So it is calculated as the product of force and displacement.
If the force increases the work done will increase and similarly, the increase in displacement increases the work done. So to push the refrigerator work should be done on the object and not by the object.
As the force is 100 N and the displacement is 5 m then, work done can be measured as
Work = Force × Displacement
Work = 100 × 5 = 500 Nm
So the work done to push the refrigerator is 500 Nm.
