Answer:
The mass of the shotput is 7.37 Kg.
Explanation:
Mechanical Force
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
F = m.a
Where a is the acceleration of the object. If the net force is zero, the object keeps moving at the same speed or keeps at rest (v=0).
A force of 140 N is exerted by a shot-putter on a shotput, which gets an acceleration of 19 m/s^2. We are required to calculate the mass of the shotput.
It can be done by solving the equation for m:
[tex]\displaystyle m=\frac{F}{a}[/tex]
Substituting the given values:
[tex]\displaystyle m=\frac{140}{19}[/tex]
m = 7.37 Kg
The mass of the shotput is 7.37 Kg.
