## 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.

## 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.
