How fast should a man weighing 60 kg?

How fast should a man weighing 60 kg?

Expert-Verified Answer. The man must run with a velocity of 5m/s so that his kinetic energy is 750 J. Given, Mass of the man = 60kg.

At what speed a person having 60kg mass should run to acquire 750 J of kinetic energy?

or v=√2Ekm=√2×75060=5m/s.

What is the kinetic energy of a jogger with a mass of 65 kg?

Expert-Verified Answer The energy formed by the motion of particles is called kinetic energy. The formula is half of the product of the mass and velocity. After solving the equation, the kinetic energy is 20.3125Joules. Hence, the correct answer is 20.3125Joules.

How fast should a boy of 40 kg run so that his kinetic energy be 5760 joules?

Expert-Verified Answer In this problem, we are given the mass of the boy, m = 40 kg, and the kinetic energy he has to achieve, KE = 5760 J. We need to find the velocity v at which he should run. Therefore, the boy should run at a speed of 12 m/s to achieve a kinetic energy of 5760 J.

Is 60 kg good for men?

The healthy weight range at your height for an adult of just about any age is 99 to 140 lbs (about 45 kg to 63.5 kg). That’s for a man or woman, whether 20, 25, or 55 years old.

Is 60 kg overweight?

A healthy weight is a weight that helps you get the most out of life. … For instance, if you’re a 1.8 metre tall adult, a healthy weight for you is generally between 60 and 80 kilograms. If you’re 1.5 metres tall, a healthy weight for you is generally between 42 and 56 kilograms.

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 to calculate 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 speed of 2 kg ball having kinetic energy of 4 j?

The speed of the 2 k g ball having a kinetic energy of is 2 m s – 1 .

Does 1kg of mass have energy?

1 Answer. If you take a mass m=1kg and turn it straight into energy, by whatever means, then indeed you will get an energy E=mc2 (a.k.a. its rest energy) out of it. where γ=1/√1−v2/c2 is known as the Lorentz factor and reduces to 1 at zero velocity (thereby giving the rest energy E=mc2).

What is the kinetic energy of a body of mass 20 kg is moving with a velocity 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 a mass of 1 kg is thrown up with a kinetic energy of 50j?

We will apply the concept of the conservation principle. Since 10% of energy is lost in overcoming air resistance. Then only 90% of kinetic energy will be left which then will be converted to potential energy. Hence, the height to which the body will rise is 4.5m.

How fast should a man of 50 kg run so that his kinetic energy will be 625j?

v = 5m/s.

What is the formula for kinetic energy per kg?

A car has a mass of 250 kg and is driven at a velocity of 10 m/s. Calculate its kinetic energy. K.E. = 12500 kg2s2. or KE = [M1L0T0] x [M0L1T-1] = [M1L2T-2].

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 fast should a man of 50 kg run?

A man of 50 kg should run at a speed of 5. 65 m/s so that his kinetic energy is 800 J. Here m is the mass of the object and v is its velocity. Therefore, the man should be running with a speed of 5.

Is 60 kg normal?

Average adult human weight varies by continent, from about 60 kg (130 lb) in Asia and Africa to about 80 kg (180 lb) in North America, with men on average weighing more than women.

What is the weight of a 60 kg person?

For example, on Earth, where the acceleration due to gravity is 9.8 m/s2, a person who has 60 kg of mass weighs 588 Newtons (132 lbs). Whereas on the moon, where the acceleration due to gravity is about 1/6 of what it is on Earth, that same 60 kg person weighs just 98 Newtons (~22 lbs).

How many calories should a 60 kg body weight?
