Question

how far will a car move in 5 seconds if it started from rest and accelerates uniformly at 2.5 metre per second square

Answer 1

Step-by-step explanation:

u = 0 m/s

a = 2.5 m/s

t = 5s

v = u + at

v = 0 + 2.5 × 5

v = 12.5 m/s

v^2 - u^2 = 2as

(12.5)^2 - 0^2 = 2 × 2.5 × s

156.25/ 5 = s

s = 31.25 m
