Question

A hockey puck slides across a frozen pond. If ice friction and air resistance are neglected, the force needed to keep the puck sliding at constant velocity is the weight of the puck divided by the mass of the puck. the mass of the puck multiplied by 10 m/s2. 0 N. equal to the weight of the puck. none of the above

Answer 1

Answer:

The force needed to keep the puck sliding at constant velocity is 0N

Explanation:

Since the ice friction and air resistance are neglected, the force needed to keep the puck sliding at constant velocity is 0N.

The acceleration due to gravity (g) will be zero since there is no ice friction and air resistance taken into consideration, and therefore,

F = m*g = m*0 = 0N
