Resistance to the motion of an automobile consists of road friction, which is almost independent of speed, and air drag, which is proportional to speed-squared. For a certain car with a weight of 19800 N, the total resistant force F is given by F = 290 + 2.5v2, where F is in newtons and v is in meters per second. Calculate the power required to accelerate the car at 0.68 m/s2 when the speed is 72 km/h. Number Units

Starting from rest, a 58.0 kg woman jumps down to the floor from a height of 0.560 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function F = 9,200 t − 11,500 t2 where F is in newtons and t is in seconds. (a) What impulse (in N⋅s) did the woman receive from the floor? (Enter the magnitude. Round your answer to at least three significant figures.)
