Answer:
3.93 m/s
Explanation:
= Mass of Ashley = 56 kg
= Mass of Miranda = 64 kg
= Initial Velocity of Ashley = 2.6 m/s
= Initial Velocity of Miranda = 5.1 m/s
v = Velocity of combined mass
As linear momentum is conserved
The speed at which they both slide down together is 3.93 m/s
Diffraction grating consists of a large number of fine slits.
Light gets split into different colors due to these slits of the diffraction grating.
Thus, diffraction grating produces a pattern of the coloured bands as each light wave passes through the slit at different speeds and different angles.
Answer:
the cannonball’s velocity parallel to the ground is 86.6m/S
Explanation:
Hello! To solve this problem remember that in a parabolic movement the horizontal component X of the velocity of the cannonball is constant while the vertical one varies with constant acceleration.
For this case we must draw the velocity triangle and find the component in X(see atached image).
V= Initial velocity=100M/S
V= Initial velocity=100M/S
Vx=cannonball’s velocity parallel to the ground
Solving for Vx
Vx=Vcos30
Vx=(100m/S)(cos30)=86.6m/s
the cannonball’s velocity parallel to the ground is 86.6m/S
Weight or matter hope it helps
It always has changing velocity
