5) In a lab, a student is asked to roll a marble down a ramp from a height that will give it a velocity of 2.0 m/s at
ramp. From what height should the marble be released?
A)
10 cm
B)
20 cm
0
40 cm
D
The mass of the marble needs to be known to find the answer.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
