A driver starts his parked car and within 5 seconds reaches a speed of 60 km/h as he travels east. What is his acceleration?

To calculate the car's acceleration, convert the velocity to meters per second to find that the car accelerates at 3.33 m/s² eastward.
The question asks for the acceleration of a car that goes from a standstill to a speed of 60 km/h in 5 seconds. First, we need to convert 60 km/h to meters per second by multiplying by 1000/3600, which gives us 16.67 m/s. Acceleration is defined as the change in velocity divided by the time taken for the change. Therefore:
Acceleration = (Final Velocity - Initial Velocity)/Time = (16.67 m/s - 0 m/s)/5 s = 3.33 m/s²
The acceleration of the car is 3.33 m/s² eastward.

The driver's acceleration is 3.33 m/s². The speed was first converted from km/h to m/s, and then the formula for acceleration: (final velocity - initial velocity) / time was used. ;

The car accelerates from 0 to 60 km/h in 5 seconds, resulting in an acceleration of 3.33 m/s² eastward. This was calculated by converting the final speed to meters per second and applying the acceleration formula. Thus, the acceleration is 3.33 m/s² toward the east.
