What constant acceleration in si units must a car have to go from zero to 60 mph in 10s. what fraction of g is this?

The acceleration of the car in SI units is 2.68m/s².

The acceleration is 0.27 times the acceleration due to gravity g.

Convert the speed in mph into m/s.

1 mile = 1609 m and 1h = 3600 s.

Therefore,

Acceleration is the rate of change of velocity. The car starts from rest , its initial velocity u = 0 and accelerates to a velocity v of 26.82 m/s in 10 s.

Use these values in the equation and calculate the acceleration.

Thus the car accelerates at a rate of 2.68 m/s².

The acceleration due to gravity g on Earth has a value 9.81 m/s².

Find the ratio

The car's acceleration is 0.27 times the value of g.
