An object of mass m = 8.0 kg is attached to an ideal spring and allowed to hang in the earth's gravitational field. the spring stretches 2.2 cm before it reaches its equilibrium position.
if it were now allowed to oscillate by this spring, what would be its frequency?
the net force on the climber is 495 n acting downwards direction.
the forces acting on the climber are:tension = 455 ngravity = mass × acceleration due to gravity = 95 kg × 10 m/s² = 950 kg-m/s²
now, the net force on the climber = gravity - tension
= 950 n - 455 n
= 495 n
(this force acts downwards as the force of gravity acts downwards)
20 meters per second at 30 seconds.
multiply 20 meters by the amount of seconds. 20*30 = 600 meters.
