Answer:

$v_1 = 91.3 m/s$

Explanation:

By energy conservation and work energy theorem we can say that after bullet hits the block, it will move on the rough floor and comes to rest

so here work done by frictional force = change in kinetic energy

so we know that

$W_f = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2$

$-\mu mg d = \frac{1}{2}m(v_f^2 - v_i^2)$

$-0.650(9.81)(7.5) = \frac{1}{2}(0 - v_i^2)$

$47.8 = \frac{1}{2}v^2$

$v = 9.78 m/s$

now by momentum conservation we have

$m_1 v_1 = (m_1 + m_2) v$

$12 v_1 = (100 + 12) 9.78$

$v_1 = 91.3 m/s$

Boyle's Law states that as the pressure on a gas increases at constant temperature the volume of the gas

elena55 [62]

Boyle’s law is P1V1 = P2V2. This shows that pressure and volume have an inverse relationship, so increase in pressure causes a decrease in volume. B is your answer

Dancers experience large forces associated with the jumps they make. For example, when a dancer lands after a vertical jump, the

Kryger [21]

Answer:

Explanation:

The head decelerates from 4 m /s to zero in .2 sec so deceleration = 4 - 0 / .2

= 20 m/s²

If F be the average force acting on head

F - mg = ma

F = m ( g + a )

= 65 ( 9.8 + 20 )

= 1937 N .

This force will be uniformly acting on head in upward direction . So during first half and second half , deceleration is same hence force F will also be same .

Which factor affects elastic potential energy but not gravitational potential energy?

Vika [28.1K]

Answer:

The correct answer is the spring constant (k)

Explanation:

Elastic potential energy: Epe = ½ * k * Δx²

k = spring constant

Δx = displacement

Gravitational ptential energy: Ep = m*g*h

g = (acceleration due to gravity)

m = mass

h = relative height of an object to some reference point
