Answer:
5 m/s 2
To
get the acceleration of a car, you need to know first the difference in the
change in speed of a car then divided by time of the change. This can be
expressed as acceleration =
(change in speed) divided by (time for the change). So 30 m/s minus 10 m/s is
equal to 20 m/s divided by 4 seconds and the quotient is 5 m/s2.
Answer:
Newton/meter
Explanation:
Acceleration is defined as the rate of change of velocity.
Therefore, the SI units of acceleration is m/sec²
However, acceleration is also involved in Newton's second law:
Force = mass * acceleration
Newton = kg * unit of acceleration
Therefre:
unit of acceleration = Newton / kg
