Q. 1 A child of mass M using a parchutereaches a termingl velocity V with the air resistance directlyproportional to the square of the child's velocity. Ifan adult of mas 3 M uses the same parchute under exactly the sameconditons, find the corrospnding terminal velocity. Q.2. A worker pushes two boxes across a frictionless horizontalfloor, as shown in the figure below. If the worker exerts ahorizontal 36 N force on the smaller crate, find the force that thesmaller crate exerts on the larger one. Q.3. A spring having a force constant of 15.0 N/cm and anunstreached length of 20 cm is pulled so that it is 23cm long. Findthe force required to strech the spring this much. Problem 3 A hockey puck leaves a player's stick witha speed of 9.9m/sadn slides 32.0m before coming to rest. find the coefficientof friction between the puck and the ice. Q.2.

When the two boxes are pushed the common acceleration a isgiven by, F=(m1+m2)a The smaller crate exerts the force F=m1a as. This is the force exerted it. The force is given for m1 by this. The force required to stretch the spring is given by F=-kx F=-15*3 F=-45N Hence we get by it.Related Questions
