Answer:

The total momentum of the carts is p = 5000 g cm/s

Explanation:

Given data,

The mass of the cart 1, m₁ = 500 g

The mass of the cart 2, m₂ = 250 g

Let the velocity of the cart 1 be, v₁ = 5 cm/s

The velocity of the cart 2 be, v₂ = 10 cm/s

According to the law of conservation of momentum, then the total momentum of the carts before and after will be the same.

Therefore,

p = m₁v₁ + m₂v₂

= 500 x 5 + 250 x 10

= 5000 g cm/s

Hence, the total momentum of the carts is p = 5000 g cm/s

A constant force of 120 N pushes a 55 kg wagon across an 8 m level surface. If the wagon was initially at rest, what is the fina

Illusion [34]

Answer:

The kinetic energy of the wagon is 967.0 J

Explanation:

Given that,

Force = 120 N

Mass = 55 kg

Height = 8 m

We need to calculate the kinetic energy of the wagon

Using newtons law

$F = ma$

$\dfrac{120}{55}=a$

$a =2.2\ m/s^2$

Using equation of motion

$v^2 =u^2+2as$

Where,

v = final velocity

u = initial velocity

s = height

Put the value in the equation

$v^2=0+2\times2.2\times8$

$v=5.93\ m/s$

Now, The kinetic energy is

$K.E=\dfrac{1}{2}mv^2$

$K.E=\dfrac{1}{2}\times55\times(5.93)^2$

$K.E=967.0\ J$

Hence, The kinetic energy of the wagon is 967.0 J

What is the kinetic energy in Joules of a 1,500kg car traveling at 75mph?What is the kinetic energy in Joules of a 1,500kg car t

Sergio039 [100]

Answer: 2812500 joules

Explanation:

Mass of car = 1500kg

Velocity of car = 75mph

Kinetic energy = ?

Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass M and velocity, V

Thus, Kinetic energy = 1/2 x mv^2

= 1/2 x 1000kg x (75mph)^2

= 0.5 x 1000kg x (75mph)^2

= 500 x 5625

= 2812500 joules

Thus, the car travels with a kinetic energy of 2812500 joules
