What is the kinetic energy of a 150kg object that is moving with a speed of 15 ms?

Kg m^2 s^-2 = Joule ,so The kinetic energy of a body of mass 150 Kg moving at 15m/s is 16875 Joules.

When a force moves an object over a rough horizontal surface?

When a force moves an object over a. rough, horizontal surface at a. constant velocity, the work done. against friction produces an increase.

When a 5 kilogram mass is lifted from the ground to a height of 10 meters?

Question: When a 5-kilogram mass is lifted from the ground to a height of 10 meters, the gravitational potential energy of the mass is increased by approximately Ca. 500J C6.

What is the kinetic energy of a 45 kg object moving at 13?

What is the kinetic energy of a 45 kg object moving at 13 m/sec? 3. Solving the equation gives a kinetic energy value of 3802.5 J. Note: The unit for energy is the same as for work: the Joule (J).

How to calculate velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

What is the kinetic energy of a 10 kg object moving at 5 ms?

The kinetic energy of the object is 125 J.

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 the kinetic energy of a car of mass 500kg moving with a velocity of 36km h?

Velocity of car, v = 36 km/hr = 36 × (5/18) = 10 m/s. Mass of car , m = 500 kg. Kinetic energy = (1/2) m v2 = (1/2) × 500 × 10 × 10 = 25000 J = 25 kJ. KInetic energy is proportional to square of velocity .

When a 1.53 kilogram mass is placed on a spring?

When a 1.53-kilogram mass is placed on a spring with a spring constant of 30.0 Newtons per meter, the spring is compressed 0.500 meter.

What is the force called when object are moving in a circular direction?

A centripetal force is a net force that acts on an object to keep it moving along a circular path.

What is it called when a force moves an object over a distance?

work. Work depends upon the force applied and distance covered. If the applied force causes an object to move to a distance, work is said to be done.

How much work is done when 10 kg of mass is lifted to height of 5 m?

∴ Work done, W =Fs =98×5J=490J .

What is an object of mass 50 kg is raised to a height of 10 m above the ground?

CALCULATION: Given that: the mass of body 50 kg, Height covered 10 m, g = 10 m/s2. P. E. = m × g × h = 50 × 10 × 10 = 5000 Joule.

What is a body of mass 5 kg lifted from the ground to a height of 8m?

We are given that the mass of the object is 5kg and it is lifted up to a height of 8m. We will put the given values in the above formula. Therefore, the work done by the gravitational force is -400J.

How do you find the speed of an object with kinetic energy?

What is the speed of a moving body of mass 30 kg has 60j of kinetic energy?

Hence, velocity or speed of body is 2 m/s.

How fast is an object with a kinetic energy of 25 j and a mass of 34 kg?

∴ The velocity of the object is 1.21 m/sec.

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.
