Covalent bonds form when two or more atoms share electrons
Net force = mass x acceleration = 250 x 3 = 750 N
Answer:
a. Wgra=786.09J
b. 1.28m
Explanation:
The change in the potential energy is the work done by the gravitational force.
For this problem you have to take into account that the total work done is given by the change in the kinetic energy
Furthermore the total work is the contribution of the work done by the skater, the gravitational force and the friction
(a) by separating Wfric you have
(b) It is only necessary to use the expression for the work done by gravitational force
