Answer:
Distance = 150 meters
Explanation:
Given the following data;
Work done = 6,000 Joules
Force = 40 Newton
To find the total distance covered by the wheelbarrow;
Workdone = force * distance
Substituting into the formula, we have;
6000 = 40 * distance
Distance = 6000/40
Distance = 150 meters
Therefore, the total distance the wheelbarrow was pushed is 150 meters.
N=3,1=2ml,0ms= +1/2 this is your answer
Answer:
The helicopter was deformed and destroyed in the inelastic collision.
Explanation:
- When two object collide there exist two way of colliding: elastic collision and inelastic collision.
- Two terms are considered during the collision: kinetic energy and momentum.
- If both of these terms are conserved in any collision then there is no significant loss of property, this is called as elastic collision.
- If only momentum is conserved but kinetic energy is converted into other forms then it is inelastic collision. In inelastic collision, the energy is lost in the form of vibration, sound etc. causing the damage to colliding object.
- Hence the deformation of helicopter was due to inelastic collision.
Answer:
See the explanation below
Explanation:
We must perform a sum of forces on the body, that sum of forces is equal to zero. That is, the body is in balance and does not move.
ΣF = 0
3 - 3 = 0
This force is negative and acts by pointing downwards.
