A 1.45 kg 1.45 kg falcon catches a 0.415 kg 0.415 kg dove from behind in midair. What is their velocity after impact if the falc
jarptica [38.1K]

Answer: The velocity is 21.5m/s

Explanation:

Let's call:

M1 and V1 as the mass and velocity of the falcon:

M1 = 1.45kg

V1 = 26.5m/s

M2 and V2 as the mass and velocity of the dove:

M2 = 0.415kg

V2 = 4.35m/s

Where both velocities are positive because both animals move in the same direction.

We can think that the interaction between both animals is a perfectly inelastic collision, because afther the interaction they move as one. Then, we have that the final velocity of both animals togheter is:

V = (V1*M1 + V2*M2)/(M1 + M2)

V = (1.45kg*26.5m/s + 0.415kg*4.35m/s)/(1.45kg + 0.415kg) = 21.5m/s

Calculate the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds.
Hoochie [10]
Acceleration = velocity/ time
Acceleration = 0.7-0.3 /30= 0.01 m/s^2
Notice that velocity is calculated the final speed minus the initial !

A skier starts from rest at the top of a 40.8 m hill, skis down a 30 degree incline into a valley, and continues up a 32.5 m hig
Volgvan

Answer:

a. 28.27 m/s

b. 12.75 m/s

c. No

Explanation:

a.

The bottom

Ek = Ep

¹/₂ * m * v² = m * g * h₁

v = √ 2 * g * h₁  = √ 2 * 9.8 * 40.8 m

v = 28.27 m/s

b.

At the top

Ek = Ep

¹/₂ * m * v² = m * g * h₁

v = √ 2 * g * h₁  = √ 2 * 9.8 * (40.8 - 32.5) m

v = 12.75 m/s

c.

No in this case the axis is the same of the motion so, the angle doesn't affect the result
