A body moving with uniform acceleration covers 25cm and 33cm in fifth ...
Solution:

Given,
Initial velocity, u = 0
Distance covered in 5 seconds, s1 = 25 cm
Distance covered in 7 seconds, s2 = 33 cm

We need to find the velocity at the end of 9 seconds, i.e. v9.

Using the equations of motion:

We know that,
s = ut + (1/2)at^2

where,
s is the distance covered
u is the initial velocity
t is the time taken
a is the acceleration

Calculating acceleration:

Acceleration can be calculated using the following formula:

a = (s2 - s1) / (t2^2 - t1^2)

where,
t1 = 5 seconds
t2 = 7 seconds

Substituting the given values, we get:

a = (33 - 25) / (7^2 - 5^2)
a = 4 cm/s^2

Calculating velocity at the end of 9 seconds:

Using the equation of motion:

v = u + at

where,
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration

Substituting the given values, we get:

v9 = 0 + (4 cm/s^2) x 9 seconds
v9 = 36 cm/s

Therefore, the velocity of the body at the end of 9 seconds from start is 36 cm/s.
