The time taken for the cheetah to accelerate from rest to 20 m/s is 2 seconds
What is acceleration?:
This can be defined as the rate of change of velocity of a body, or it can be defined as the change in velocity of a body, per time. The S.I unit of acceleration is m/s²
To calculate the amount of time it takes a cheetah to accelerate from rest to 40 m/s, we use the formula below.
Formula:
- a = (v-u)/t...................... Equation 1
Where:
- a = acceleration of the cheetah
- v = Final speed of the cheetah
- u = initial speed of the cheetah
- t = time taken
make t the subject of the equation
- t = (v-u)/a................. Equation 2
From the question,
Givnen:
- a = 20 m/s²
- v = 40 m/s
- u = 0 m/s (from rest)
Substitute these values into equation 2
- t = (40-0)/20
- t = 2 seconds.
Hence, The time taken for the cheetah to accelerate from rest to 20 m/s is 2 seconds
