Answer: The net force acting on the car 1,299.3 N.
Explanation:
Mass of the car = 710 kg
Initial velocity of the car of the ,u= 37 km/h= 10.27 m/s 
Final velocity of the car,v = 120 km/h = 33.33 m/s
time taken b y car = 12.6 sec
v-u=at
The net force acting on the car 1,299.3 N.
The radius of the circular motion at the given speed is 1.56 m.
The given parameters;
- <em>speed of the rock, v = 2.5 m/s</em>
- <em>acceleration of the rock, a = 4 m/s²</em>
<em />
The radius of the circular motion is calculated by using centripetal acceleration formula as follows;
Thus, the radius of the circular motion at the given speed is 1.56 m.

The Ohio Constitution lays out a three-part government with legislative, executive, and judicial branches just like the US Constitution. But the Ohio Constitution incorporates more elements of direct democracy and has a stronger legislative branch relative to the executive. Hopes this helps!

Displacement is the area under the velocity/time graph. So for example this object's displacement in the first 3 seconds is (1/2)(3sec)(12.5 m/s)= 18.75m. (and then it starts backing up, displacement decreasing, after 3sec when velocity is negative).
But This object is never speeding up. Its velocity is smoothly decreasing at (25/6) m/s^2 (the slope of the graph). So the answer to the question is actually zero.
