mixer [17]
<h2>~<u>Solution</u> :-</h2>
  • Here, the <u>moment arm</u> is defined as follows;

The magnitude of two forces, which when acting at right angle produce resultant force of VlOkg and when acting at 60° produce resultant of Vl3 kg. These forces are D. gravitational force of attraction towards the centre of the earth. A sample of metal weighs 219 gms in air, 180 gms in water, 120 gms in an <em>unknown fluid</em>.

In a car with a mass of 4,000 KG is accelerating at a rate of 2m/s2 and hits a tree what force does it have
Ilia_Sergeevich [38]

According to Newton's second law of motion, the acceleration of a body is directly proportional to the force acting on the body and inversely proportional to its mass. The formula for this law is

F=ma

=4000kg * 2m/s 2 =8000N

A 12.0-g bullet is fi red horizontally into a 100-g wooden block initially at rest on a horizontal surface. After impact, the bl
allochka39001 [22]

Answer:

v_1 = 91.3 m/s

Explanation:

By energy conservation and work energy theorem we can say that after bullet hits the block, it will move on the rough floor and comes to rest

so here work done by frictional force = change in kinetic energy

so we know that

W_f = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2

-\mu mg d = \frac{1}{2}m(v_f^2 - v_i^2)

-0.650(9.81)(7.5) = \frac{1}{2}(0 - v_i^2)

47.8 = \frac{1}{2}v^2

v = 9.78 m/s

now by momentum conservation we have

m_1 v_1 = (m_1 + m_2) v

12 v_1 = (100 + 12) 9.78

v_1 = 91.3 m/s
