a catapult is used to project a stone of mass 50g. if the rubber of the catapult has an elastic constant of 200N/m and was stretched 5cm, what speed can it give to the mass​

Respuesta :

Answer:

3.16 m/s

Explanation:

Elastic energy in the rubber = kinetic energy of the stone

EE = KE

½ kx² = ½ mv²

v = √(kx²/m)

Given k = 200 N/m, x = 0.05 m, and m = 0.050 kg:

v = √(200 N/m (0.05 m)² / 0.050 kg)

v = √10 m/s

v ≈ 3.16 m/s

Round as needed.

speed can it give to the mass​ 3.16 m/s

Elastic strength inside the rubber = kinetic power of the stone

EE = KE

½ kx² = ½ mv²

v = √(kx²/m)

Given k = 200 N/m, x = 0.05 m, and m = 0.050 kg:

v = √(200 N/m (0.05 m)² /0.050 kg)

v = √10 m/s

v ≈ 3.16 m/s

Why does mass boom with velocity?

So when we think of mass as strength, we are able to start to recognize why an item will boom its 'mass' as it accelerates. As an item increases in speed, so does the quantity of electricity that it has, this strength is what we confer with as 'the growth in mass' (simply do not forget, that is inertial mass).

While an object is traveling at an excessive velocity, its resistance to acceleration does not exchange, and its ability to enjoy gravity does not change. The mass of an object, therefore, does not alternate whilst it travels at an excessive pace.
