Question

1. If a Creature Cat's Ferrari With an initial speed of 15 m/s, accelerates at a rate of 60/m/s/s for 5 s, what

will the final speed be?

Answer 1

v = 315m/s

Step-by-step explanation:

a = v - u /t

a = acceleration 60m/s2

v = final speed

u = initial speed 15m/s

t = time 5 secs

Therefore

60 = v - 15 /5

Cross multiply

v - 15 = 60 x 5

v - 15 = 300

Add 15 to both sides

v - 15 + 15 = 300 + 15

v = 315m/s
