Question

11. A force produces an acceleration of 5.0 cms-2.When it acts on a body
of mass 20 g. Find the force in newtons
[ ]
a) 2.0x10-N
b) 3.0x10-'N
c) 1.0x10-N
d) 1.0x10-4 N​

Answer 1

Answer:

We convert mass m to kilograms using Appendix D (1 u = 1.661 x IO" 27 kg). ... We apply Newton's second law (specifically, Eq. 5-2). ... then Newton' s second law gives the third force as F 3 = ma -F x - F 2 =(-34 N) í ...
