Answer:
False
Explanation:
The object could be in a constant velocity and the sum of both the external torques and the external forces on an object is zero. Newton's first law states that when the total net force is 0 or there is zero force, the object could be at rest OR remain in constant velocity. It's not necessary at rest.
Do you mean 12 km/h because this is a measurement of distance
Answer:
<em>The mass of the shotput is 7.37 Kg.</em>
Explanation:
<u>Mechanical Force</u>
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:
Substituting the given values:
m = 7.37 Kg
The mass of the shotput is 7.37 Kg.
I am 95% sure the answer is Newton hope this helps (sorry if I’m wrong I’m a little sleep deprived)
