1. A frictionless $$23\mathrm{kg}$$ fan sled (a sled forced to move because of the propulsion provided by the fan) is travelling forward with a velocity of $$2.9\mathrm{m}/\mathrm{s}$$. The fan sendsan impulse burst of 30.0 $$\mathrm{N}$$ for $$13.2\mathrm{s}$$, adding to the sled's momentum. a. Calculate the impulse that the fan exerts. b. What is the initial momentum of the fan sled? c. What is the final momentum of the fan sled? d. What is the final speed of the fan sled?
