What is a body of mass 20 kg moving with velocity 5m s?

What is a body of mass 20 kg moving with velocity 5m s?

Detailed Solution The correct answer is 250 J. Given, mass (m) = 20 kg, velocity (v) = 5 ms-1. So, the kinetic energy of the object is (½)∗20∗52 = 250 J.

What is the speed of a 1.0 x10 3 kilogram car?

A 1.0 × 10³-kilogram car travels at a constant speed of 20 meters per second around a horizontal circular track.

What is the change in momentum of a body of mass 20 kg moves with an acceleration of 2 meters per second square?

Rate of change of momentum of body is 40 N. Q.

What is the momentum of a 20 kg body moving with a velocity of 10 m per second?

Hence the momentum of the body is 200 kg. m/s.

What is the velocity of a 900 kg car?

What is the velocity of 1000 kg car?

[Expert Answer] a 1000kg car has a velocity of 17m/s.

What is the speed of an object of 1 kg mass with a kinetic energy of 50 J?

Mass (m)= 1 kg. Velocity (v)= 10 m/s. ∴The Kinetic Energy of the object is 50 J. ∴ The correct option is the 4th.

What is 1 kgf equal to?

The deprecated unit-kilogram-force(Kg-f) is the force exerted by one kilogram of mass in standard earth gravity which is defined as exactly 9.80655 m/s2. Thus 1 Kg-f is equal to 9.8 N.

What is 9.8 N equal to?

So, the weight of one kg is 9.8 N or we can say that One kgw = 9.8 N. Mass and weight are different things.

What is the formula of change in momentum?

Step 1: Identify the mass of the object, , the initial velocity of the object, , and the final velocity of the object, . Step 2: Calculate the change in momentum, which is equal to the impulse, , using the formula Δ p = m ( v f − v i ) .

What is a body of mass 1 kg and velocity 10m s?

Given: Mass (m)= 1 kg. Velocity (v)= 10 m/s. ∴The Kinetic Energy of the object is 50 J.

What is the kinetic energy possessed by an object of mass 20 kg is moving with an uniform velocity of 5 ms 1?

The Kinetic Energy of the object will be 250 J. So option 4 is correct.

What is the linear momentum of a body of mass 10 kg moves with velocity 5 Metre per second?

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

What is a body of mass 2kg is thrown up at a velocity of 25m s?

Solution: A body of mass 2 kg is thrown up with a speed of 25 m/s. Its maximum potential energy will be 625 J.
