A body of mass 20 kg has a momentum of 120 kgm/s.find its vvelocity?
well,
p = mv
plug in your numbers and solve for v.
PE =13kg (3.6m)(9.8m/s)
=46.8kg m (9.6m/s)
=458.64 j
To find the velocity of a body, we can use the formula for momentum (p) which is defined as the product of mass (m) and velocity (v).
The formula for momentum is:
p = m * v
Given:
Mass (m) = 20 kg
Momentum (p) = 120 kgm/s
We can rearrange the formula to solve for velocity (v):
v = p / m
Now substitute the given values:
v = 120 kgm/s / 20 kg
The units "kg" in the numerator and denominator will cancel out, leaving us with the velocity in meters per second (m/s).
v = 6 m/s
Therefore, the velocity of the body is 6 m/s.
