When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4500 N . The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 760 N , including the "friction" of turning the truck's drivetrain. What is the magnitude of the force the car applies to the truck?

3740N

Explanation:

The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.

The formula for force is force = mass x acceleration.

To find mass, simply divide the force by the acceleration

acceleration=1.1m/s²

Mass=4500−760=3400N

Therefore, Mass x acceleration

=1.1m/s²x3400=3740N

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
