- Using energy considerations, calculate the average force (in N) a 69.0 kg sprinter exerts backward on the track to accelerate from 2.00 to 6.00 m/s in a distance of 25.0 m, if he encounters a headwind that exerts an average force of 30.0 N against him. (Enter a number.)Markup A Text 76.Calculate the power output needed for a 950-kg car to climb a 2.00° slope at a constant 30.0 m/s while encountering wind resistance and friction totaling 600 N. Solution Image Link Form TO Redact Tool ✓A 20.0-kg crate sits at rest at the bottom of a15.0-m-long ramp that is inclined at above the horizontal. Aconstant horizontal force of 290 N is applied to the crate to push itup the ramp. While the crate is moving, the ramp exerts a constantfrictional force on it that has magnitude 65.0 N. (a) What is thetotal work done on the crate during its motion from the bottom tothe top of the ramp? (b) How much time does it take the crate totravel to the top of the ramp?
