A force of 10N act on a body of mass 5kg for one second than change in momentum is
The change in momentum is given by the formula:
Δp = FΔt
where Δp is the change in momentum, F is the force applied, and Δt is the time for which the force is applied.
In this case, F = 10N and Δt = 1 second. The mass of the body is m = 5kg.
So,
Δp = FΔt
Δp = 10N * 1s
Δp = 10 Ns
Now, using the definition of momentum:
p = mv
where p is momentum, m is mass, and v is velocity.
We can rearrange this formula to find the velocity of the body:
v = p/m
So,
v = Δp/m
v = 10 Ns / 5kg
v = 2 m/s
Therefore, the change in momentum is 10 Ns and the velocity of the body is 2 m/s.
The change in momentum can be calculated using the equation:
Change in momentum = Force * Time
Given:
Force = 10 N
Time = 1s
Substituting these values into the equation:
Change in momentum = 10 N * 1 s
Change in momentum = 10 Ns
Therefore, the change in momentum is 10 Ns.
