Respuesta :
Velocity equals distance divided by time. V= 12 divided by 3.0 = 4 m/s
The velocity of a cart in a time of 3.0 sec starting from rest will be 4 m/sec. Velocity is a time-based component.
What is velocity?
The change of displacement with respect to time is defined as the velocity. Velocity is a vector quantity.
The given data in the problem is;
The initial velocity is,[tex]\rm u = 0 \ m/sec[/tex]
The displacement of the cart is,[tex]\rm d = 12\ m[/tex]
The time taken is,[tex]\rm t = 3.0 \ sec[/tex]
The velocity is to be found is,[tex]\rm v[/tex]
The velocity is found as;
[tex]\rm v = \frac{d}{t} \\\\ \rm v = \frac{12}{3.0} \\\\ v=4.0 \ m/sec[/tex]
Hence, velocity of a cart will be 4 m/sec.
