Question

A force of 5n gives a mass m1 and acceleration of 10 m/s and a mass m2 an acceleration of 20 m/s what would be acceleration if both the mass were tied together

Answer 1

Given that:
Force 1 = 5N
Acceleration 1 =10m/s^2

Force 2 = 5N
Acceleration =20m/s^2


Mass 1 = force/acceleration [as mass ×acceleration =force]
Mass 1 = 5/10
= 0.5

Mass 2 = 5/20
= 0.25



Again, force = 5N
Mass 1 +mass 2 = 0.5+0.25
=0.75
force = mass×acceleration
5 = 0.75× acceleration
Acceleration =5/0.75
= 20/3 or 6.67 m/s^2 (approx)

Answer 2

Answer:

force=5N

acceleration =10m/s^2

mass (m1)=?

force=mass×acceleration

mass=force/acceleration

=5/10

0.5kg

then

other body

force=5 Newton

acceleration=20 m/s

mass(m2)=?

similarly

m2=5/20

=0.25kg

then

both masses tied together

(0.25+0.5)=0.3kg

then

acceleration=?

force=5N

mass=0.3kg

acceleration =force/mass

=5/0.3

=16.66m/s^2
