Answer:
They will both hit the ground at the same time
Explanation:
The answer is wheel and axle
Answer:
Explanation:
Assuming that velocities remain negligible,
The work will be equal to the change in potential energy of the center of mass
mass is 30 m(5 kg/m) = 150 kg
W = 150(9.8)(30/2) = 22,050 J ≈ 22 kJ
Answer:
3.76 N
Explanation:
We are given that two force vectors point in opposite directions.
Let


Because second force act in opposite direction.
We have to find the magnitude of sum of two forces.
We know that triangle law of addition
Resultant sum=
Substitute the values then we get
Resultant sum of two forces=
Resultant sum of two forces=3.76 N
Hence, the magnitude of sum of two forces=3.76 N
