Since both hv same mass and elsstic collision, so their velocity will exchange. Bob A will stop and bob B will move with speed of A just before the collision.
Speed will be = squreroot ( 2*g*L)
L is length of pendulum
Answer:
According to the Conservation of Momentum,
Momentum of the gun = momentum of the bullet
M(gun)×V(gun)=m(bullet)×v(bullet)
4kg × V = 0.3kg × 600m/s²
V = (0.3 × 600)/4 = 45 m/s
The recoil velocity on the gun is <em><u>45 m/s</u></em>
<h3><u>45 m/s</u> is the right answer.</h3>

Ball 1 Has uchanging motion because it continually goes up no matter what. Ball 2 has no motion. And ball 3 changing motion because it goes from not moving to moving. Hope this helps
Answer:
Explanation:
mass of the alloy = 35.2 g
temperature t of the alloy = 93° C
heat loss by alloy = mc ( t₁ - t₂) where t₁ = 93 and t₂ = 31.1° C
heat loss by alloy = 2178.88 c where c is the specific heat capacity of the alloy
heat gained by water = m cw ( t₂ - t₁ ) where t₁ of water = 22° C and t₂ of water = 31.1° C
heat gained by water = 8338.294
heat gained = heat loss
2171.84 c = 8338.294
c specific heat capacity of the alloy = 8338.294 / 2178.88 = 3.83 J/g.K
