Answer:
Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.
Explanation:
It let me answer now
Hope This Helped ;)
The slope of the line on a velocityversus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.
Okay so you have to find acceleration first. I used v=vo+at. Plug in the numbers and you get -11.9m/s^2 as your constant acceleration. Then plug acceleration into d=vi(t)+1/2(a)t^2
d=(40m/s)(3.34s)+1/2(-11.9m/s^2)(3.34s)^2
d=68.6m

5 km/hr because he thinks it moves in the same speed of his...
