A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5m/s/s. Determine the mass of the encyclopedia

Verified Answer :

Tann

a=5m/s
F=15N
by the formula, F = m × a
15N = m × 5m/s
m = \(\frac{15}{5}\)             
By simplification(division), 
m = 3
Thus, mass of the Encyclopedia will be 3kgs.

All the Best. :D
