If F is 91 newtons what force does block A m 1 5 kg exert on

If F, is 91 newtons, what force does block A (m 1 5 kg) exert on block B (m2 3 kg) in the following figure? Force of A on B = | Number ewtons m, my

Solution

solution:

F₁= 91 N

is net force on mass (A+B) combo

hence acceleration of the system suppose a

then

F= (net mass)(a)

91=8a

a=(91/8)m/sec²

now force exerted by A on B will be

F= (mass of B)(common acceleration)

= (3)(91/8)N

= 34.125 N
