Answer:
3000 hurs
Explanation: just divide 150000 by 50 and get 3000
As we know that the formula of kinetic energy will be

now here we know that
m = 2 kg
v = 1 m/s
so from the above equation we have


The 48 and 47 are different atomic masses, this is caused by having a different number of neutrons.
Answer:
height is the answer i'm pretty sure.
