A constant force of 3.3 N to the right acts on a 16.6 kg mass for 0.54 s. (a) Find the final velocity of the mass if it is initially at rest. m/s to the right(b) Find the final velocity of the mass if it is initially moving along the x-axis with a velocity of 1.27 m/s to the left. m/s to the left

The answer to your question is below

Explanation:

Data

F = 3.3 N

m = 16.6 kg

t = 0.54 s

a)

vf = ? m/s

vo = 0 m/s

Process

1.- Calculate the acceleration of the body

    F = ma

solve for a

    a = F/m

    a = 3.3/16.6

    a = 0.198 m/s²

2.- Calculate the vf

    a = (vf - vo)/t

solve for vf

    vf = at + vo

    vf = (0.198)(0.54) + 0

   vf = 0.11 m/s

b)

The acceleration will be the same

    vf = (0.198)(0.54) - 1.27

    vf = 0.11 - 1,27

    vf = -1.16 m/s   to the left
