Two bodies,A(of mass 1kg) and B(of mass 3kg) are dropped from heights ...
Problem: Find the ratio of time taken by the two bodies A and B of mass 1kg and 3kg respectively, dropped from heights of 16m and 25m respectively.
Solution:
We know that the time taken by a body to fall from a certain height is given by the formula:
t = √(2h/g)
where t is time, h is height, and g is acceleration due to gravity (9.8 m/s²).
For Body A:
Given, h = 16m and m = 1kg
Using the formula, we get:
t(A) = √(2*16/9.8)
= √(32/9.8)
= 2*√(2/9.8)
= 2*√(20/98)
= 2*√(10/49)
= 2*√(10)/7
For Body B:
Given, h = 25m and m = 3kg
Using the formula, we get:
t(B) = √(2*25/9.8)
= √(50/9.8)
= 2*√(50/98)
= 2*√(25/49)
= 2*√(25)/7
= 10/7
Ratio of time taken:
So, the ratio of time taken by Body A and Body B is:
t(A)/t(B) = (2*√(10)/7)/(10/7)
= 2/5
Therefore, the required ratio is 2:5.
Solution:
We know that the time taken by a body to fall from a certain height is given by the formula:
t = √(2h/g)
where t is time, h is height, and g is acceleration due to gravity (9.8 m/s²).
For Body A:
Given, h = 16m and m = 1kg
Using the formula, we get:
t(A) = √(2*16/9.8)
= √(32/9.8)
= 2*√(2/9.8)
= 2*√(20/98)
= 2*√(10/49)
= 2*√(10)/7
For Body B:
Given, h = 25m and m = 3kg
Using the formula, we get:
t(B) = √(2*25/9.8)
= √(50/9.8)
= 2*√(50/98)
= 2*√(25/49)
= 2*√(25)/7
= 10/7
Ratio of time taken:
So, the ratio of time taken by Body A and Body B is:
t(A)/t(B) = (2*√(10)/7)/(10/7)
= 2/5
Therefore, the required ratio is 2:5.
