What is the kinetic energy of a body if mass is 2 kg and momentum 2 ns?

2 J
1 J. 2 J.

How much work is needed to be done on a body of mass 2kg to give a momentum of 30 km s?

final velocity = v = 30 m/s. F= 2×30 = 60N.

What is the momentum of a body of mass 10kg moving with a velocity of 0.5 m s?

Answer: The linear momentum of a body of mass 10 kg moving with velocity 5 m/sec is 50 kg m/s.

How is kinetic energy calculated?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

What is the value of gravitation potential energy of the body of mass 2 kg which is projected vertically upwards with a speed of 3 m s?

The maximum gravitational potential energy of the body is 9 J.

How much work is needed to be done on a ball of mass 50kg to give it a momentum of 5kg m/s 1?

So, work done = Change in KE of the ball =12mv2=12×0.05×1002=250 J. How much work is needed to be done on A ball of mass 100 g to give it a momentum of 5 kgm/s. The linear momentum of a ball of mass 50g is 0.5kgms−1.

What is the momentum of an object of mass 10 kg moving with a velocity of 5 Metre per second?

Thus, the momentum is 50kg m/s.

What is the momentum of a body of 2 kg?

A body of mass 2 kg is moving with a momentum of 10 Kgm/s. What will be the force needed to increase its kinetic energy by four times in 10 seconds? – Quora A body of mass 2 kg is moving with a momentum of 10 Kgm/s.

What is the initial speed of a body with mass 10-2 kg?

A body of mass m = 10 -2 kg is moving in a medium and experiences a frictional force F = – kv 2. Its initial speed is v o =10 ms -1 If after 10 s, its energy is 1/8mv 20, the value of k will be

How do you calculate momentum with mass and velocity?

Momentum Equation for these Calculations: \\( p = mv \\) Where: p = momentum. m = mass. v = velocity. The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third.

How many joules does it take to change 2 m/s?

Assuming that the force acts in the same direction, velocity of 2 m/s will increase in 10 sec by 0.04 × 10 = 0.4 m/s and becomes 2.4 m/s. This comes to 4.4 joules. If the force acts in the opposite direction, the velocity of 2 will become 1.6 m/s and change in KE = 3.6 J. A force of 100N acts on a body for 10 seconds.
