Answer:
option C.
Explanation:
The correct answer option C.
When the rock tied at the end of the string and rotated the rock has two accelerations acting on it. One is tangential acceleration and another one is radial acceleration.
The rock has that tendency to move tangential but due to centripetal force, it is rotating in a circular path.
But when the string breaks the rock will move in a straight path.
This is because of the inertia because rock tendency is to be in a straight path but due to external force it was moving in a circular path but when the string breaks it moves in a straight line.
Answer:No it means that the object is at equilibrium
Explanation:
The sum of force acting opposite is equal to zero if forces are equal.
Straight line distance between their home and the store can be solve using cosine law. first is solve the angle which is180 - 45 = 135 degree
C^2 = a^2 + b^2 - 2ab cos(135)c^2 = 5^2 + 5^2 - 2(5)(5) cos(135)c^2 = 85.35c = 9.24 km is the straight line distance between their home and the store
