A toy car sta rts from rest and accelerates at 1.50 m/s2 [E] for 5.25 s. What is the final velocity, of the car? Show your work.?

Remembering to round to 3 sig. figs. (to match the data supplied), the calculations in the other answers are correct.
But we are asked for the velocity, not the speed. So the correct answer must include direction: 7.88m/s [E]

Vf = Vi + a*t = 0 + 1.5*5.25 = 63/8 = 7 7/8 = 7.875 or about 7.88m/s <<<

v = vo + at
v = 0 + (1,50)(5,25) = 7,875 m/s
