What is an object of 10 kg is moving with a speed of 2m s?
What is an object of 10 kg is moving with a speed of 2m s?
Speed of the object (v) = 2 m/s. Kinetic Energy (K.E) = ½ mv2. = ½ (10)(2)2 ⇒ 20 joules. The kinetic energy of the object is 20 J.
What is the speed of a moving body of mass 10 kg has 20 tools of kinetic energy?
The correct Answer is:2 m/s. A moving body of mass 10 kg has 20 joules of kinetic energy.
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 is the kinetic energy of a body of mass 10 kg moving with a speed of 5 meters per second square?
= – 125 J (nagative sign indicates work done is opposite to the direction of motion)
What happens when a mass of 20 kg moving with a speed of 10 Metre per second collides with another stationary?
A mass of 20 k g moving with a speed of 10 m s – 1 collides with another stationary mass of 5 k g . As a result of the collision, the two masses stick together.
What is the kinetic energy of a 10 kg object moving at 5 ms?
The kinetic energy of the object is 125 J.
What is the velocity of an 10 kg object with a kinetic energy of 180 J?
The kinetic energy of an object of mass 10 kg moving with a velocity of 6 ms-1 is 180 J. kinetic energy, a form of energy that an object or a particle has by reason of its motion.
How do you calculate the speed of a moving object?
Speed is the rate at which an object’s position changes, measured in meters per second. The equation for speed is simple: distance divided by time. You take the distance traveled (for example 3 meters), and divide it by the time (three seconds) to get the speed (one meter per second).
How do you calculate the work done to take an object of mass 10 kg?
Detailed Solution. F = m.g = 10 × (-9.8) (The negative sign is taken because the displacement is opposite to the direction of the force.) W = -1960 J (The negative sign appears because the direction of the force is opposite to the direction of displacement so that the work done is negative.)
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 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 an object that has a mass of 10 kg and 125 J of kinetic energy?
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 total energy of a body of mass 10 kg moving at a height 2 m with uniform speed of 2 metre per second?
So, net energy of object is 220 Joule.
At what constant speed does a body of mass 10 kg move?
An object of mass 10 kg moves at a constant speed of 10 ms−1. A constant force that acts for 4 s on the object gives it a speed of 2 ms−1 in the opposite direction.
What is the kinetic energy of an object of mass 10 kg falls from height 10 m?
E = mgh, g is acceleration due to gravity So, the kinetic energy gained by the body is 980 J.
What is the net force acting on an object of mass 10 kg moving with a constant speed of 10 m per second?
⇒F=m(v−u)t=10(−2−10)4=−30 N.
What is an object of mass 20kg is moving with a velocity of 5m s?
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 acceleration of an object with a mass of 10 kg and a net force of 30 N?
By taking the formula F=m*a, and rearranging the make a the subject, we get a=F/m. Then by substituting in the values given we can work out that a=30/10=3. The units of acceleration are ms-2 so hence, the object will accelerate at 3ms-2.
How much force is required to change velocity of a body of mass 10kg from 2m s to 6m s?
To find the force required to change the velocity of a body from 2 m/s to 6 m/s in 2 seconds, we can use Newton’s second law of motion, which states that force (F) is equal to the rate of change of momentum. So, the force required to change the velocity of the body from 2 m/s to 6 m/s in 2 seconds is 20 Newtons.
