a projectile covered 20 meter total HORIZONTAL distance crangel and its horizontal velocity is 10 METER per second. what is ANGLE of inclination?

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
