A force of unknown magnitude is applied to push a 115kg bobsled down a flat, frictionless surface with an acceleration of 7.8 m/s2. What is the net force on the sled?

Answer:

Explanation:

Since we have no friction and we also have no angle of inclination, this is a straightfoward force problem, where

Answer:Explanation:Since we have no friction and we also have no angle of inclination, this is a straightfoward force problem, where

F = ma

Filling in,

F = (115)(7.8) so

F = 9.0 × 10¹ N
