Question

a force of 450 n accelerates a box across a frictionless surface at a rate of 15 m/s2. what is the mass of the box?

Answer 1

Use the equation:
Resultant force= mass of body×acceleration(F=ma)
450N is the resultant force acting on the box since there is no friction to oppose it.
To find mass of box,
450=m×15
m=450÷15=30kg
