Question
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
F = ma
Filling in,
F = (115)(7.8) so
F = 9.0 × 10¹ N
