Question

Solve any one problem with formula force

Answer 1

Answer:

Explanation:

Force = mass X acceleration

Let mass is 2 and acceleration is 9.8 then force is 2 X 9.8=19.6

Answer 2

Explanation:

F = d(momentum)/dt

= d(mv) /dt

= m d(V)/dt + v d(m)/dt

since mass is taken as constant for proving F = ma

F = m d(v)/dt + 0 ( m is constant)

F = m a........( a = d(v)/ dt)

Hence proved....
