One type of BB gun uses a spring-driven plunger to blow the BB from its barrel. (=) Calculate the force constant (in N/m) of its plunger's spring if you must compress it 0.180 m to drive the 0.0560 kg plunger to a top speed of 25.0 m/s. N/m (b) What force (in N) must be exerted to compress the spring? (Enter the magnitude.) NA mass attached to the end of a spring is oscillating with a period of 2.25 s on a horizontal frictionless surface. The mass was released from rest at r = 0 from the position * = 0.0600 m. () Determine the location of the mass at t = 5.38 s? m (b) Determine if the mass is moving in the positive or negative x direction at t = 5.38 s? O positive x direction O negative x direction Jdeal MaterialsFish are hung on a spring scale to determine their mass (most fishermen feel no obligation to report the mass truthfully). (=) What is the force constant (in N/m) of the spring in such a scale if it stretches 8.50 com for a 11.0 kg load? N/m (b) What is the mass (in kg) of a fish that stretches the spring 5.50 cm? kg (c) How far apart (in mm) are the half-kilogram marks on the scale? mmA 0.480 kg mass hung from a spring stretches it 0.160 m. [b) (=) How much (in m) does it stretch two such identical springs if they are hung in parallel, as in (a) of the figure above? m (c) How much (in m) does it stretch the two springs if they are hung in series, as in (b) of the figure above? m (c) Calculate the effective force (in N/m) constant of a single replacement spring in each case.
