Well most of the particles did pass through and a few were deflected. but i think the answer is A
Answer:
a
Explanation:
a is the answer
attached is the solution
yes it will
4.95s≈5s
Use equation :
h=G*t²/2
h=120m ----hight of cliff
G=9.81m/s²
t=?
-----------------------
120m=9.81m/s²*t²/2
240m=9.81m/s²*t²
t²=240m/ 9.81m/s²
t²=24.46s
t=√24.46s²
t=4.95 s≈5s
