(20 sec)/(40 swings) = 0.5 sec/swing
Answer:
B. the force of on the truck due to the collision is exactly equal to the force on the car.
Explanation:
At the time of collision between two objects of unequal or equal masses two forces emerge at the point of collision .They are called action and reaction force . According to third law of Newton , they are equal . So in the instant case of collision between car and truck , force on both of them will be equal.
Answer:
magnitude of the resultant of forces is 11.45 N
Explanation:
given data
force F1 = 6N
force F2 = 8N
angle = 240°
solution
we get here resultant force that is express as
F(r) = 
..............1
put here value and we get
F(r) = 
F(r) = 11.45 N
so magnitude of the resultant of forces is 11.45 N
The sum of the two vectors in A, B, and C is equal to the sum of the two vectors above the line. The sum of the two vectors in D isn't.
