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

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
