Notes: .  For Newton’s Law calculations, mass must be expressed in kg and velocity must be expressed in m/s. 1.  An automobile weighs 2000 lb.  Calculate the weight of the car in N and its mass in kg. 2.  is the acceleration of a car that moves from a speed of 2.5 m/s to a speed of 25 m/s during a time of 6.5 s? 3.  An astronaut has a mass of 120 kg.  She recedes from her spacecraft using spurts of gas from a small unit on her back.  If the force generated by the gas spurt is 50 N, calculate her acceleration. 4.  A steady 45 N horizontal force is applied to a 15 kg object on a table.  The object slides against a friction force of 30 N.  Calculate the acceleration of the object in m/s. 5.  A man with a mass of 110 kg slides down a vertical pole with an acceleration of 9 m/s2.  is the frictional force acting on the man? 6.  A space ship has a mass of 75,000 kg.  net force is required to accelerate it to 20 m/s2 ? 7.  A net force of 3500 N accelerates a car from rest to 46 km/h in 5 s.  is the mass of the car? 8.  A force of 3.2 N is applied to an 8.5 gram rifle bullet.  is the bullet’s acceleration? 9.  An automobile is pulled by a horizontal tow line, with a force of 950 N.  If its acceleration is 1.0 m/s2, calculate the mass of the automobile. 10. is the weight in Newtons of a 250 gram box of breakfast cereal?
