A car is moving east at 35 m/s. I it accelerates at 20 m/s squared for a period of 22 seconds, what is its final velocity?

Sagot :

luana
[tex]acceleration=\frac{velocity_{final}-velocity_{initial}}{time}\\\\ 20\frac{m}{s^2}=\frac{velocity_{final}-35\frac{m}{s}}{22s}\ \ \ |*22s\\\\ 440\frac{m}{s}=velocity_{final}-35\frac{m}{s}\ \ \ |Add\ 35\frac{m}{s}\\\\ velocity_{final}=475\frac{m}{s}[/tex]
