Find the acceleration (m/s²)of cheetah if it acquires a velocity of 135km/hr in 2s after the start
please answer it fastly
Answers
Explanation:
Velocity of cheetah = 135 km/hr or (135*5/18) m/s
Time = 2 sec
Acceleration = ?
We know that acceleration is the rate of change of velocity with respect to time
Hence,
Acceleration = Velocity / time
\frac{135 \times \frac{5}{18} }{2}

Acceleration = 1.04 m/s^2
Given - Velocity and time
Find - Acceleration
Solution - Acceleration of Cheetah is 18.75 metre/second²
Acceleration can be calculated by the formula = change in velocity/time.
Firstly converting velocity from kilometre/hour to metre/second.
Velocity in metre/second = 135*1000/3600
Velocity in metre/second = 37.5 metre/second
Keep the values in the formula to find the acceleration of the Cheetah.
Acceleration = 37.5/2
Acceleration = 18.75 metre/second²
Acceleration of Cheetah is 18.75 metre/second²
