Question

The linear momentum of a particle as a function of time t is given by P = a + bt, where a and b are positive constants. What is the force acting on the particle?

Answer 1

Hii dear,

# Answer- F = b

# Explaination-
Given is linear momentum,
P = a + bt ...a,b=+ve integers

Force = Impulse/time
Force = change in momentum/time

F = dP/dt
F = d(a+bt)/dt
F = 0 + b
F = b

Hence, force acting on particle will have magnitude b.

Hope that solved your query...

Answer 2

HLO MATE HERE U GO

Given linear momentum ,p = a + bt

FORCE ,F = ....?

Force = rate of change of momentum

F = dp /dt

= d/dt ( a + b t ) = b

Therefore Force on the body = b.
