una fuerza de 57 N actua sobre un cuerpo y este se acelera a razon de 3m/s2 ¿cual es la masa delcuerpo? y cuanto se aceleraria si la fuerza aplicada fuera de 3,6 N?

a and b sometimes have a positive value

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
