Question

A car traveling 24 m/s begins to decelerate at a constant rate of 5 m/s2. After how many seconds does the car come to a stop?

Answer 1

\[v(t) = 24ms^{-1}\]
\[\alpha(t)=5ms^{-2}\]
\[\int\limits_{}^{}\alpha(t)dt = v(t)\]
\[\int\limits_{}^{} 5 dt=5t\]
\[5t=24\]
\[t=\frac{24}{5}s\]
\[t=4.8s\]
