15. An object is dropped in an unknown
planet from height 50 m, it reaches the
ground in 2 s. The acceleration due to
gravity in this unknown planet is
(a) g = 20 ms? (b)g = 25 ms
(c) g = 15 ms (d)g = 30 ms
t


PLEASE GIVE ME A CLEAR DIAGRAM NOT SOLVE THIS
​

Answer 1

Answer:

(B) 25 ms

Explanation:

S = ut+1/2gt^2

50 = 0×2+1/2g×2×2

50 = 2g

g = 50/2

g = 25ms

s-height = 50

u-intial velocity

t-time

g-acceralation due to gravity
