a 2500 kg car going 35 m/a hits a 4000kg truck that is sitting still. What is the velocity of the truck if the car transfers all

lianna [129]

Answer:

Velocity of truck is 21.875 m/s.

Explanation:

Given:

Mass of the car (m) = 2500 kg

Initial speed of the car (u) = 35 m/s

Mass of the truck (M) = 4000 kg

Initial speed of the truck (U) = 0 m/s (Rest)

As per question, the total momentum of the car gets transferred to the truck.

Therefore, the final momentum of the car is 0.

Momentum is given as the product of mass and velocity.

So, if momentum becomes zero means the velocity becomes 0.

Therefore, final velocity of the car (v) = 0 m/s

Let the final velocity of truck be 'V' m/s.

Now, during collision, the total momentum remains conserved.

Initial momentum = Final momentum.

Initial momentum of car + Initial momentum of truck = Final momentum of car + Final momentum of truck.

⇒ $mu+MU=mv+MV\\\\2500\times 35+4000\times 0=2500\times 0+4000\times V\\\\87500+0=0+4000V\\\\4000V=87500\\\\V=\frac{87500}{4000}\\\\V=21.875\ m/s$

Therefore, the velocity of the truck is 21.875 m/s.

Charra [1.4K]

The motor full load currents listed in NEC Tables 430.247 through 430.250 shall be used to determine the capacity of motor circuit conductors and short-circuit and ground-fault protection. This is further explained below.

<h3>What is currents?</h3>

Generally, Moving through an area of water or air where there is less movement than the water or air itself, an eddies

In conclusion, Using the full load currents indicated in NEC Tables 430.247 through 430.250, the capacity of motor circuit conductors and short-circuit and ground-fault protection for motors should be determined.

What is the difference between an epiphyseal line and an epiphyseal plate?

Alika [10]

Answer: Accordingly, what is the difference between an epiphyseal plate and an epiphyseal line? The Epiphyseal plate contains cartilage used for producing bone. The Epiphyseal line is formed after the epiphyseal plate has stopped producing bone). The Periosteum is the covering of a bone.

An iron anchor of density 7850.00 kg/m3 appears 183 N lighter in water than in air.

andrew11 [14]

<h2>a) Volume of anchor is 0.019 m³</h2><h2>b) Weight of anchor in air is 1463.17 N</h2>

Explanation:

a) Weight loss in water = Volume of object x density of water x acceleration due to gravity

183 = Volume of anchor x 1000 x 9.81

Volume of anchor = 0.019 m³

b) Weight = Mass x acceleration due to gravity = Volume x Density x acceleration due to gravity

Weight of anchor in air = Volume of anchor x Density of anchor x acceleration due to gravity

Weight of anchor in air = 0.019 x 7850 x 9.81 = 1463.17 N

Weight of anchor in air = 1463.17 N

Newton’s Third Law describes two different bodies acting on each other.
now you've considered the action and reactions based on d ball, but have u considered the force the athlete exacts on the ground which is external to the athlete-ball system, now the ground in which the athlete stands exert a force back on the athelete-ball system which causes the ball to accelerate
