Two dogs play tug of war with a rope toy that has a mass of 0.50 kg. If one dog pulls on the toy with a force of 140.0 N, and the other dog pulls in the opposite direction with a force of 138.0 N, what is the horizontal acceleration of the toy?

Answers

Answer:[tex]4\ m/s^2[/tex]

Explanation:

Given

mass of toy [tex]m=0.5\ kg[/tex]

Force by first dog [tex]F_1=140\ N[/tex]

Force by second dog is [tex]F_2=138\ N[/tex]

Net force on the dog is

[tex]F_{net}=F_1-F_2=140-138[/tex]

[tex]F_{net}=2\ N[/tex]

and [tex]F_{net}=ma[/tex]

[tex]a=\dfrac{F_{net}}{m}[/tex]

[tex]a=\dfrac{2}{0.5}[/tex]

[tex]a=4\ m/s^2[/tex]

So, horizontal acceleration of the toy is [tex]4\ m/s^2[/tex]

A bullet of 5 gm is fired from a pistol of 1.5 kg. If the recoil velocity of pistol is 1.5 m/s,

find the velocity of bullet.​

Answers

Answer:

-450 m/s

Explanation:

Momentum is conserved.

p₀ = p

0 = (1.5 kg) (1.5 m/s) + (0.005 kg) v

v = -450 m/s

compare magnetic properties of iron and steel​

Answers

Answer: Iron and steel are two separate metallic elements.

Explanation:

The following are the differences between magnetic properties of iron and steel.:

1. Iron get magnitized quickly under the influence of magnetic field whereas the steel magnitized slowly.

2. The iron looses its magnitism when magnetic field is removed but steel retains the magnitism for long when magnetic field is removed.
