Question

. A train's velocity is slowly decreasing as it approaches a station About 1 km before it reaches (1 point) the station, several stowaways jump off the train. What happens to the amount of acceleration if the force remains constant? Assume the train is traveling in the positive direction. OIt will become less negative. OIt will become more negative. OIt will remain the same. OIt will become more positive. 7. Which is not true about the variables in the relationshipFma? fI pont) OAcceleration is directy proportional to mass. OForce is directly proportional to mss. OForce is directly proportional to acceleration. Acceleration will double if force is doubled. S. A force causes a mass of 4 kg to bave an acceleration of 8ms Suppose something causes the (1 poînt) mass to be one-quarter of its original amount. What will happen to the acceleration if the amount of force used remains the same? OIt will decrease to 2 m/s OIt will remain the same. OIt wll increase to 32 m/s2 OIt will increase to 16 m/s 9. A force of 1 N will cause a mass of I kg to have an acceleration of1 m s. If a fo of ( pont) newtons is applied to a mass of 1 kg, what will be its acceleration? O1 m/s O1/6 m/s O36 m/s 10. On earth, a block is placed on a frictionless table. When a 50 N horizontal force is applied to (1pomt) the block, it accelerates at 4.0 m's". Suppose the block and table are set up on the moon. When a horizontal force of 25 N is applied to the block, what is the acceleration? O2.4 m/s2 O3.4 m's 2.0 ms O3.2 m/s2

Explanation / Answer

6) D, it wiil become more positive.

7) A, According to newton's second law of motion the are of changes of momentum is directly proportional to external force applied. F=m.a
