Question

V = u + 2at

Where v is the final velocity (in m/s), u is the initial velocity (in m/s), a is the acceleration (in m/s²) and t is the time (in seconds).
Find v when u is 19 m/s, a is 3 m/s², and is 21 seconds.

Answer 1

V=145

Explanation:

V=U+2at

v=19+2×3×21

v=19+126

v=145

Answer 2

145 m/s

Explanation:

v = u + 2at

v = 19 + 2(3)(21)

v = 19 + 126

v = 145
