Question

1. The head of a rattlesnake can accelerate 50.00 m/s2 in striking a victim. If a car

could do as well, how long would it take to reach a speed of 100.0 m/s from rest?
​

Answer 1

2.000 s

Step-by-step explanation:

Given:

a = 50.00 m/s²

v = 100.0 m/s

v₀ = 0 m/s

Find: t

v = at + v₀

(100.0 m/s) = (50.00 m/s²) t + (0 m/s)

t = 2.000 s
