Answer: $85.80
Explanation: 100kg is equalvilent to 220 lbs, then you multiply 220 by .39 and then you have your answer :)
Answer:
Option B, two walls and the floor
Explanation:
The distance should be measured from the point where at least the three axed meet.
Two walls and the floor are equivalent to three axes.
Vertical wall 1 = Y Axis
Horizontal wall2 = X Axis
Floor = Z Axis
Thus, the distance should be measured from the point where two walls and one floor meet.
Option , B is correct
Answer:
Potential refers to stored energy while kinetic is energy in motion. All energy, whether potential or kinetic, is measured in Joules (J).

Complete Question
A truck going 15 km/h has a head-on collision with a small car going 30 km/h. Which statement best describes the situation?
A. the truck has the greater change of momentum because it has the greater mass
B. the car has the greater change of momentum because it has the greater speed
C. neither the car nor the truck changes its momentum in the collision because momentum is conserved
D. they both have the same change in magnitude of momentum because momentum is conserved
E. none of the above is necessarily true
Answer:
D. They both have the same change in magnitude of momentum because momentum is conserved
Explanation:
In order to get a good understanding of the solution above we define some
concetps
Momentum
This is defines quantified motion and can be mathematically represented as
Momentum = Mass of the body × Velocity of the body
According to the Law of conservation of momentum states that when two particles collide together in a system that is being isolated that their total momentum before and after their collision is equal this means that the momentum lost by the truck would be the same as the momentum gained by the small car
