fake cord made for bungee jumping is being tested a weight of 800 Newtons is attached to one end of the budgie cord then the weight is released from the tall tower and it moves downwards when the elastic cord is fully extended it exert an opposite force of 900 and on the way what would happen if the elastic cord extended a maximum force of only 700 newtons on the weight​

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?

70 give a real life example showing how sensory neurons work with the motor neurons

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
