Question

If a creature cats Ferrari, with an initial speed of 10 m/s, accelerate at a rate of 50 m/s/s for 3 seconds, what will it's final speed be?

Answer 1

160 m/s because you start off with 10 and go up by 50*3 which is 150 then add that with the begging speed to achieve 160m/s.

Answer 2

Vf = x
Vi = 10 m/s
A = 50 m/s²
T = 3


Vf = Vi + at

x = 10 + 50(3)

x=160

Final Velocity is equal to 160 m/s
