Question

Two blocks of masses 1 kg and 3 kg placed in contact are acted upon by a force of 80 N. The acceleration of 1 kg mass will be a)40 ms-1 b)30 ms-1 c)10 ms-1 d)20 ms-1

Answer 1

Answer:

bkkiikkkkkkkkkkkkkkkkkkkk

Answer 2

Answer:

D) 20 ms-1

Explanation:

F = ma

a = F / ( m1 + m2 )

a = 80 / ( 3 + 1 )

a = 80 / 4

a = 20 ms-2

Acceleration of m2 will be the 60 ms-2.
