250/2= 125
Because almost all of the force is done by the weight of the person and the mechanism of the swing itself, when you push someone you only give them an increase in velocity, the acceleration comes from the weight at first and then from gravity when the person is coming down, which is why we bend our legs when coming down
The acceleration of a car with the mass of 1,980kg with a net horizontal force of 1,000 N is 0.51m/s².
<h3>HOW TO CALCULATE ACCELERATION?</h3>
The acceleration of a body can be calculated using the following formula:
a = F ÷ m
Where;
- a = acceleration (m/s²)
- F = Force (N)
- m = mass (kg)
According to this question, a car has a mass of 1980kg and horizontal force of 1000N. The acceleration is as follows:
a = 1000/1980
a= 0.51m/s²
Therefore, the acceleration of a car with the mass of 1,980kg with a net horizontal force of 1,000 N is 0.51m/s².

Answer:
the frame of reference requires deciding where the object's initial position is and which direction will be considered positive.
Explanation:
(20 miles) x ( 1/45 hour/mile) =
(20/45) (hour) = <em>
4/9 hour = </em>26 minutes 40 seconds
