What is the kinetic energy of a ball of mass 2kg moving with velocity 10m s?

The correct answer is 100 J.

What is a solid mass 2 kg moving with velocity 10 ms?

A solid of mass 2 kg moving with velocity 10 m/s strikes an ideal weightless spring and produces a compression of 25 cm in it. Calculate the force- constant of the spring. Ans. 3200 N/m.

What is the velocity of a body of mass 2kg moving in the xy plane?

Velocity of a body of mass 2 kg moving in x-y plane is given by v⃗ =(2i^+4tj^)m/s, where t is the time in second.

What is the 2 formula for velocity?

Speed and Velocity Instantaneous velocity is the velocity of a body at any given time. Average velocity is the total displacement by total time and is given by v = △x/△t where ∆x is the total displacement of the body and ∆t is the time.

What is the formula for velocity to mass?

Mass is measured in (kg), and velocity is measured in meters per second (m/s). The SI unit for momentum is kg • m/s. You can rearrange the equation to calculate velocity if you know momentum and mass, Velocity = Momentum/Mass, or to calculate mass if you know momentum and velocity, Mass = Momentum/Velocity.

What is the kinetic energy of a body of mass 2 kg moving with a velocity of 0.1 m?

The correct answer is: 0.01 J With an increase in its height the potential energy increases.

What is the kinetic energy of a body of mass 2 kg moving with a velocity of 0.1 ms?

Expert-Verified Answer K.E = 0.01 J. Hence, the kinetic energy of a body is 0.01 Joule.

What’s the formula for kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

What is a mass of 10 kg moves with velocity of 4m s?

Answer and Explanation: K = 1 2 m v 2 = 1 2 ( 10 kg ) ( 4 m/s ) 2 = 80 J .

What object of mass 2 kg is projected up with velocity?

a body of mass 2 kg is projected upwards with a velocity 4 metre per second. The kinetic energy of the body just before striking the ground is what? answer:16J.

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

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

What is the velocity of mass of 0.5 kg?

A particle of mass 0.5 kg travels in a straight line with velocity v=ax3/2 where a=5m−1/2s−1.

What is the velocity of a particle of mass 2?

Velocity of a particle of mass 2 Kg varies with time t according to the equation v=(2t^i+4^j) m/s.

What is the velocity that a body of 2 kg mass should have in order to have kinetic energy of 100 joules?

Expert-Verified Answer kinetic energy = 1/2 × mass × velocity². velocity² = 100. that is 10 m / s. the velocity of a body of mass 2 kg having kinetic energy of 100 joules is 10 m / s.

What is the velocity of a particle of mass 1kg?
