A child climbing a ladder is transforming kinetic energy into potential energy.
High density because it is obvious it will be hard to rip and tear.
Answer:
B. positive; negative.
Explanation:
From the viewpoint of Principle of Energy Conservation and Work-Energy Theorem, we notice that gravity represents a conservative force, associated with gravitational potential energy, whereas air resistance is a non-conservative force, associated with dissipated work. Therefore, the work done by gravity is positive and work done by air resistance is negative. Therefore, the correct answer is B.
Answer:
Linear momentum= Mass*Velocity
P=mv
P=60*10
P=600Kg m/s
