m = mass = 5 kg

v_{i} = initial velocity = 100 m/s

v_{f} = final velocity = ?

I = impulse = 30 Ns

Using the impulse-change in momentum equation

I = m(v_{f} - v_{i})

30 = 5 (v_{f} - 100)

v_{f} = 106 m/s

How do i calculate the kinetic energy
Stella [2.4K]

The kinetic energy is found at 150 J. The work-energy theorem is applied in the given equation.

<h3>What is Kinetic energy?</h3>

The energy possessed by the body by the virtue of motion is known as Kinetic energy. It is found as the product of mass and the square of the velocity.

The given data in the problem is;

The mass is, m=0.15 kg

Force, F=300 N

Distance,d=0.50 m

From the work-energy theorem, kinetic energy is equal to the work done.

Work done = Kinetic energy

\rm F  \times d  = KE \\\\ KE= 300 \times 0.50 \\\\ KE=150 \ J

Hence, kinetic energy is found at 150 J.

To learn more about the kinetic energy, refer to the link;

Car A travels from New York to Miami at a speed of 25 m/s. Car B travels from New York to Chicago, also at a speed of 25 m/s. Ar
arsen [322]

Answer:

Not Equal.

Explanation:

As the direction from New York to Miami (due South) is different from the direction from New York to Chicago (due West), the 2 velocities are not equal despite having the same magnitude. If both cars are to travel to the same destination at same speed, their velocities would be equal.

A car starting at rest accelerates at 3m/s² How far has the car travelled after 4s?​
stepladder [879]

Answer:

24m

Explanation:

you can use the formula

s=ut+1/2at²

s=0+1/2(3)(4)²

=1/2(3)(8)

=24m
