plz it's a request that dont answer if u don't know.. nd its really urgent!

S=ut+1/2×-g×t*2=(20×3)-(1/2×10×9)=15m

okay dude...
tysm! ♥
u should clear this doubt with teacher, kk then only u will clear about the concept
kay!
Check wheather it is a printing mistake or not...
dude, ive written in the copy, which was written by the teacher in the board.
Kk, pls clear it with tr...
sure.
Kk, then
yeah!

so simple
given that,
u = 20m/s
a= -g = -10 m/s²
s = ?
t= 3s
by the Newton's 2nd law of motion
s= ut+1/2at²
s = 20×3 + 1/2 ×-10 × 3²
s = 60 - 1/2 90
s = 60 - 45
s = 15 metre
the answer is 15 metre
please mark it as brainliest answer if you have satisfied
