The acceleration of each object will be 2.31 m/s².While the direction for mass 1 is down, mass 2 is left and mass 3 is up.

<h3>What is tension force?</h3>

The tension force is described as the force transferred through a rope, string, or wire as it is pulled by opposing forces.

The tension force is applied along the whole length of the wire, pulling energy equally on both ends.

From Newton's second law, the net force is equal to the product of the mass and acceleration. Forces and tension acting upward are positive while the downward is taken as negative.

Foer mass m₁ only vertical force is considered.

\rm \sum F_y=ma_y \\\\ + T_{12}-m_1g =-m_1a \\\\ -T_{12}+39.2 \ N=(4.00 \ kg )a

For mass m₂ both horizontal and verticle force is considered;

\rm  \sum F_x=ma_x \\\\ -T_{12}+f+T_{23}\\\\ -T_{12}+\mu_kN+T_{23} \\\\ T_{12}-0.350(9.80 \ N)-T_{23}=(1.00 \ kg)a

\rm \sum F_y =ma_y \\\\ N-m_2g=0

Foer mass m₃ only vertical force is considered.

\rm \sum F_y=ma_y \\\\ T{23}-m_2g=+m_3a \\\\ T_{23}-19.6 \ N=(2.00 \ kg)a

Adding  all the obtained forces we get;

\rm +39.2 \ N-3.43 \ N-19.6 N=(7.00 \kg) a\\\\ a=2.31 \ m/s^2

Hence, the acceleration of each object will be 2.31 m/s².While the direction for mass 1 is down, mass 2 is left and mass 3 is up.

A family car has a mass of 1400 kg. In an accident it hits a wall and goes from a speed of 27 m/s to a standstill in 1.5 seconds
horrorfan [7]

Answer:

The force has been reduced by 8018 N

Explanation:

The impulse exerted on the car during the crash is equal to the product of the force exerted and the duration of the collision, and it is also equal to the change in momentum of the car. So we can write:

F\Delta t = m\Delta v

where:

F is the force exerted on the car

\Delta t is the duration of the collision

m = 1400 kg is the mass of the car

\Delta  v=-27 m/s is the change in velocity of the car

We can re-write the equation as

F=\frac{m\Delta v}{\Delta t}

In the 1st collision, the time is 1.5 seconds, so the force is

F_1=\frac{(1400)(-27)}{1.5}=-25,200 N

In the 2nd collision, the time is increased to 2.2 seconds, so the force is

F_2=\frac{(1400)(-27)}{2.2}=-17,182 N

Therefore, the force has been reduced by:

F_2-F_1=-17,182-(-25,200)=8018 N
