Object a of mass m is released from height h, whereas object b of mass 0.5m is released from height 2h. what is the ratio of the velocity of object a to that of object b immediately before they hit the ground?
a. 1: 2
b. 1.41 : 1
c. 1: 1.41
d. 1: 4
e. 1: 1

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

490 n

f=125n a=2.5m/s2

i dont have a visual in front of me, but i can you reason to try to get the right one. the graph should look like this, 0 to 6 there is a spike, 12 to 14 there should be a very low point. slight increase in the graph at 12 to 14, and flat 14 to 18
