1.	13. A ball is dropped from certain height such that thedistance travelled in last second is equal to thedistance travelled in first three second. Find its height
Answer» Answer: Hello! This may help you for SURE! Formula USED: sn=u+g/2(2n−1) Answer:125m Explanation: The distance covered in first 3 second s=1/2gt^2 =1^2×10×3^2 =45 Ball TAKES 'n' seconds to fall to the GROUND. The distance covered in the NTH second is sn=u+g/2(2n−1) =10/2(2n−1) =10n−5 Therefore 45=10n−5 n=5=t Therefore h=12*gt^2 =12×10×25 =125m

Answer: Hello! This may help you for SURE!

Formula USED:

sn=u+g/2(2n−1)

Answer:125m

Explanation:

The distance covered in first 3 second

s=1/2gt^2

=1^2×10×3^2

=45

Ball TAKES 'n' seconds to fall to the GROUND. The distance covered in the NTH second is

sn=u+g/2(2n−1)

=10/2(2n−1)

=10n−5

Therefore 45=10n−5

n=5=t

Therefore h=12*gt^2

=12×10×25

=125m
