Question

16. Is an object speeding up or slowing down for the following two conditions? a. The object's velocity and acceleration are in opposite directions: b. The object's velocity and acceleration are in the same direction: 17. For an object in free fall (neglect air resistance), what constant do we use for the acceleration of the object (state its direction and numerical value including units)? 18.Page 43 of the text gives the "General Problem Solving Strategy. Give a short description of the four parts of this strategy.

Explanation / Answer

16)

a) as the speed will be decreasing due to opposite acceleration so it's slowing down

b) speed will increase due to acceleration in same direction so it's speeding up

17) the direction of g is towards the center of earth and the value is 9.8 m/s^2

18) as the page no-43 is not available so sorry I can't help you with that
