Question

the head of a rattle snake can accelerate up to 50 m/s2 while attacking its prey, if a car was capable of achieving this acceleration, how much time would the car need to reach 100 km/h from rest?
I need the procedure and the answer

Answer 1

• And like all snakes, their first weapon is not size or strength, but sheer speed. According to research published in March 2016, an average snake strike lasts somewhere between 44 and 70 milliseconds

• They found that all snakes could accelerate at more than 160 metres per second squared (ms−2) and reach speeds approaching 3 metres per second. This enables the animals to cover average distances of 13.6–16.7 centimetres in 66–74 milliseconds

Answer 2

Answer:

t = 0.55 second

Explanation:

a = 50 m/s^2, u = 0 , v = 100×1000/3600 m/s,

t =?

v= 27.7 m/s

v = u + at

27.7 ÷ 50 = t

t = 0.55 second
