Question

03. A body (mass 0.5 kg) is constrained to move East-
wards. A force of 20 N acts on the body driected
30° east of north. The acceleration produced in
the body due to the force will be
(1) 40 m/s
(2) 20 m/s
(3) 2013 m/s? (4) Zero
​

Answer 1

Explanation:

force in East

F=20cos60°=10N

and acceleration

a=F/m=10/0.5=20m/s^2
