Question

A car accelerates uniformly from rest, described by v = at and s = 0.5at². If you need to find the time t and you only know the displacement s and acceleration a, how would you proceed?

Accepted Answer

Isolate t in s = 0.5at² and solve for t.

Answer

Estimate t based on typical acceleration values.

Answer

Use graphical methods to estimate t.

Answer

Use v = at directly to find t.
