A steady horizontal force lasting for 2.10 s gives a 1.25 kg object an acceleration of 3.20 m/s2 on a frictionless table. What impulse does this force give to the object?
 
  A) 25.7 kg m/s
  B) 10.9 kg m/s
  C) 8.40 kg m/s
  D) 4.00 kg m/s
  E) 2.63 kg m/s

Question 2

On planet X, the absolute pressure at a depth of 2.00 m below the surface of a liquid nitrogen lake is 5.00  105 N/m2. At a depth 5.00 m below the surface, the absolute pressure is 8.00  105 N/m2. The density of liquid nitrogen is 808 kg/m3.
 
  (a) What is the atmospheric pressure on planet X?
  (b) What is the acceleration due to gravity on planet X?
