A car of mass 750 kg has an initial speed of 75 mph. Traveling in a straight line, its speed is increased uniformly to 120 mph in 2.0 miles. What is the net force that was exerted?

Explanation:

ESTE PROBLEMA ES MEJOR HACERLO EN SI. PRIMERO CONVIERTES

LA VELOCIDAD INICIAL Y LA VELOCIDAD FINAL A m/s

= 33.52 m/s      v = 53.67 m/s      x = 3220 m

PRIMERO ENCUENTRAS LA ACELERACIÓN DEL COCHE CON LA ECUACIÓN

DE GALILEO GALILEI

a = =

AHORA CON LA ACELERACIÓN USMOS LA SEGUNDA LEY DE NEWTON

F = 75 kg() = 40.9 N

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
