In summary, the acceleration of a car can be calculated using the formula: acceleration = (final velocity - initial velocity) / distance. In this case, it would be (32 km/h - 54 km/h) / 65 m = -0.338 m/s^2. The time it takes for the car to slow down from 54 km/h to 32 km/h in 65 m can be calculated using the formula: time = (final velocity - initial velocity) / acceleration. In this case, it would be (32 km/h - 54 km/h) / -0.338 m/s^2 = 67.16 seconds. It is possible for the car to slow down faster than 0.338

FAQ: Kinematics: Slowing Car from 54 to 32 km/h in 65 m
How do you calculate the acceleration of a car slowing down from 54 km/h to 32 km/h in 65 m?
The acceleration can be calculated using the formula: acceleration = (final velocity - initial velocity) / distance. In this case, it would be (32 km/h - 54 km/h) / 65 m = -0.338 m/s^2.
How long does it take for the car to slow down from 54 km/h to 32 km/h in 65 m?
The time can be calculated using the formula: time = (final velocity - initial velocity) / acceleration. In this case, it would be (32 km/h - 54 km/h) / -0.338 m/s^2 = 67.16 seconds.
Is it possible for the car to slow down faster than 0.338 m/s^2?
Yes, it is possible for the car to slow down faster than 0.338 m/s^2. This value represents the average acceleration over the entire distance of 65 m. The car could have a higher acceleration at the beginning and then gradually decrease to this value.
How does the mass of the car affect its deceleration?
The mass of the car does not directly affect its deceleration. The deceleration is primarily determined by external factors such as friction and air resistance. However, a heavier car may require more force to slow down, which could affect the deceleration rate.
Can you use this information to predict the stopping distance of the car?
No, this information alone is not enough to predict the stopping distance of the car. Other factors such as the initial velocity, acceleration, and external forces need to be taken into account. Additionally, real-world conditions may vary and affect the stopping distance.
