Answer:
momentum formula = Mass × Velocity
The equation which shows the relationship between frequency, wavelength and velocity of particle is given as,
Here, f is the frequency, v is the velocity and
is the wavelength. The frequenc
C is the answer to your question!
Answer: Arrow B
Explanation:
Arrow B best best represents the path the ball follows after the string breaks.
This is because the described situation is related to <u>uniform circular motion</u>, in which the tangential velocity is the linear velocity vector that is <u>always tangent to the trajectory</u> and is the distance traveled by the ball in its circular motion in a period of time.
Hence, if this circular motion suddenly stops, the ball will fly in a direction that is tangent to that circle.
PART a)
By energy conservation we can say
divide whole equation by mass "m" and plug in all given data
so gymnast will reach the floor with speed 5.21 m/s
PART b)
Now the gymnast bend her knees by 0.1 m and comes to rest
so here we will have
now the force on the gymnast will be
so during landing the force will be 6798.5 N
