How to Calculate the Mass of a Barbell Thrown by a Clown?
What is the mass, in kilograms, of the barbell if the clown recoils with a speed of 0.485 m/s and the barbell is thrown with a speed of 8.5 m/s?
A. 10.965 kg
Answer:
The mass of the barbell is 10.965 kg if the clown recoils with a speed of 0.485 m/s and the barbell is thrown with a speed of 8.5 m/s.
Calculating the mass of an object thrown by a clown can be an exciting and challenging task. In this scenario, we have a clown recoiling with a speed of 0.485 m/s and a barbell being thrown with a speed of 8.5 m/s. To determine the mass of the barbell, we can use the law of conservation of momentum.
According to the law of conservation of momentum, the total momentum before the throw is equal to the total momentum after the throw. The equation can be expressed as:
m1v1 + m2v2 = m1v'1 + m2v'2Given that the clown recoils with a speed of 0.485 m/s and the barbell is thrown with a speed of 8.5 m/s, we can substitute the values into the equation and solve for the mass of the barbell, m2.
On simplifying the equation, we find that the mass of the barbell is 10.965 kg. It's incredible how the mass of an object can be calculated using the principles of momentum and velocity. Physics can be fun and fascinating when applied to real-life scenarios like this one.
