The velocity of the stuntman, once he has left the cannon is 5 m/s.
The right option is O A. 5 m/s
The Kinetic energy of the stuntman is equal to the elastic potential energy of the spring.
<h3 /><h3>Velocity: </h3>
This is the ratio of displacement to time. The S.I unit of Velocity is m/s. The velocity of the stuntman can be calculated using the formula below.
⇒ Formula:
- mv²/2 = ke²/2
- mv² = ke².................. Equation 1
⇒ Where:
- m = mass of the stuntman
- v = velocity of the stuntman
- k = force constant of the spring
- e = compression of the spring
⇒ Make v the subject of the equation
- v = √(ke²/m)................. Equation 2
From the question,
⇒ Given:
- m = 48 kg
- k = 75 N/m
- e = 4 m
⇒ Substitute these values into equation 2
- v = √[(75×4²)/48]
- v = √25
- v = 5 m/s.
Hence, The velocity of the stuntman, once he has left the cannon is 5 m/s.
The right option is O A. 5 m/s

An object MASS is equal to the amount of matter it has
Let's look at the equation for momentum (p)
Where p is the momentum, m is the mass and v is the velocity.
If an object doubles in mass then we have 2m and so:
If it doubles in mass, then the momentum is also doubled.

Answer:
Explanation:
The candela (symbol: cd) is the SI base unit of luminous intensity, which is defined as the power emitted by a light source in a certain direction, weighted by the luminosity function. A standard candle produces light with a luminous intensity of around 1 cd.
