On an ice rink, Manuel pushes off the wall with 540 N of force. If his mass is 72.0kg, what is his
acceleration on the skates (assume that the friction is essentially 0).

7.5m/s2

Explanation:

Force applied = 540 N of force.

mass = 72.0kg

acceleration on the skates = ?

Recall that Force is the product of mass of an object and the acceleration by which it moves.

Force = mass x acceleration

540N = 72.0kg x acceleration

Acceleration = 540N/72.0kg

= 7.5m/s2

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
