c) the distance moved in meter

Answer 1

A resultant force of 25 Newton acts on mass
of 0.5 kg standing from rest.
find: a) the acceleration in m/s square
b) the final velocity after 20 seconds
c) the distance moved in meter

Answer 2

a = F/m = 25/ 0.5 = 50 m/s^2

v = Vinitial + a * t = 0 + 50 * 20 = 1,000 m/s

x = initial +Vinitial * t + ( 1/2) a *t^2 = 0 + 0 + 25* 400
= 25 * 400 = 10,000 meters
