How long does it take for a car o slow from 54 km/h to 32 km/h over 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.
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.
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.
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.
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.
