Solving the equation (1) and(2)
Next lets assume that the front wheels contact with the ground N_A = 0
Choosing the critical case
Answer:
(a). The average acceleration is 0.08 m/s².
(b). The uncertainty in the acceleration is ±0.0135 m/s².
Explanation:
Given that,
Initial velocity
Final velocity
Time
(a). We need to calculate the average acceleration
Using formula of acceleration
Put the value into the formula
(b). We need to calculate the uncertainty in the velocity
Using formula of the uncertainty
Put the value into formula
We need to calculate the uncertainty in the time
Using formula for time
We need to calculate the uncertainty in the acceleration
Using formula for acceleration
Put the value into the formula
Hence, (a). The average acceleration is 0.08 m/s².
(b). The uncertainty in the acceleration is ±0.0135 m/s².
