Question

calculate the force
required to move a stationary object of mass 3kg from rest to velocity at 8m/s in 2 seconds

Answer 1

hey dear
here is your answer

given data:
v = 8
m = 3kg
t = 2 seconds
u = 0

by using 1st equation of motion, we will find acceleration firstly
v = u+at
8 = 0+2a
a = 4 m/s^2

force = mass×acceleration
force = 4×3 = 12N

hope it helps
have a good day ☺

Answer 2

as force is mass × acceleration
mass=3kg
acceleration=8/2=4ms^-2
mass×accelaration =
3×4(Newton)
12newton
