What is the velocity of a 0.06 kg ball moving with 75j of energy?
What is the velocity of a 0.06 kg ball moving with 75j of energy?
Expert-Verified Answer The velocity of the 0.06 kg ball with 75 J of energy is 50 m/s, calculated using the kinetic energy formula and the given mass and energy values. In this case: The kinetic energy (KE) is given as 75 J. The mass (m) of the ball is 0.06 kg.
What is the KE of a 3kg ball that is rolling at 2m s?
KE= ½ m v2 = ½ (3kg) (2 m/s)2 = 6 Joules 8.
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.
Expert-Verified Answer Mass of the tennis ball x 10 = Mass of the basketball. This means, The mass of the basketball is ten times the mass of the tennis ball.
How do you calculate energy velocity?
We can calculate the velocity, or speed, of an object by dividing the change in distance by the change in time. This can then be used to calculate the kinetic energy of an object by taking the velocity squared times the mass times one half.
What is the momentum of a 6.0 kg bowling ball with a velocity?
p=6×2.2=13.2kg m/s. Q.
What is the kinetic energy of a 2kg ball dropped from a height of 10m?
Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant. ∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m. ∴ Kinetic Energy = 980 J.
What is the KE of a 0.2 kg ball thrown with a velocity of 6m s?
The formula for kinetic energy is: KE = (1/2)mv^2 Now, we can plug in the values for mass and velocity: KE = (1/2)(0.2 kg)(6 m/s)^2 KE = (1/2)(0.2 kg)(36 m^2/s^2) KE = (0.1 kg)(36 m^2/s^2) KE = 3.6 kg m^2/s^2 So, the kinetic energy of the ball is $\boxed{3.6 \text{ J}}$ (Joules).
What is the kinetic energy of a 7.26 kg bowling ball?
Expert-Verified Answer Kinetic energy; Kinetic energy is the energy that an matter or object has due to its motion. Where m is the mass and v is the velocity or speed. Therefore, the Kinetic energy possessed by the bowling ball while rolling is 14.52J.
What is the SI unit for velocity?
What is the SI unit of velocity? The SI unit of velocity is metres per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).
How do you find K in physics?
As a formula, it reworks Hooke’s Law and is expressed through the equation: k = – F/x. Where k is the spring constant, F is the force applied over x, and x is the displacement by the spring expressed in N/m.
What is the SI unit of energy?
The SI unit of energy is same as that of work, which is joule (J).
What is the speed of a 100g ball that has a kinetic energy of 20j?
⟹v=20 m/s.
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 .
What is the velocity of the 3 kg ball after the collision?
The velocity of the 3 kg ball is 4 m/s after the collision.
What will be the wavelength of a ball of mass 0.5 kg moving with a velocity of hundred Metre per second?
⇒ λ= 6.62×10−340.5×100 =1.32× 1035m. Q. Q.
