Question

Use the formula s = 1/2at² to find the value of s given the

following values of a and t.
a=30
ft
2
sec²
and t = 6 sec

Answer 1

Explanation:

let's write this properly that we are not confusing ourselves :

s = ½×a×t²

a = 30 ft/sec²

t = 6 sec

so,

s = ½ × 30 ft/sec² × (6 sec)² = ½ × 30 ft/sec² × 36 sec² =

= ½ × 30 ft × 36 = 15 ft × 36 = 540 ft

s = 540 ft
