Answer:
The girl will move with constant velocity
Explanation:
If after a certain time t_0 the velocity of the girl is v_0 =gt_0 and the upward force on the girl due to rope is mg ,where g is gravitational acceleration. Then the girl will move down with the constant velocity v_0 .
The girl will move with constant velocity,as explained above.
Answer:
What is the kinetic energy of a bicycle with a mass of 14 kg traveling at a velocity of 3 m/s? Physics ... K=12mv2=12×14 kg × (3 m/s)2=63 Joule.
1 answer
63 Joule Explanation: K=12mv2=12×14 kg × (3 m/s)2=63 Joule
Explanation:
K=12mv2=12×14 kg × (3 m/s)2=63 Joule.
63 Joule Explanation: K=12mv2=12×14 kg × (3 m/s)2=63 Joule
Answer:
0.000507 kg/m
Explanation:
L = Length of string
T = Tension
= Mass density of string
E denotes the E string
D denotes the D String
Frequency is given by
So
The mass density of the E string is 0.000507 kg/m
Answer:
100N
Explanation:
because newton's third law of motion states that if body A exerts a force on the body B, then Body B will exert an equal force but opposite in direction force on body A
so if the fly experienced 100N, then the car will also experience 100N
hope you get it
