ma=1/2*kx^2 10*9.8=1/2*700*x^2 x approximately equals 0.529m
wer did u get this -> ma=1/2*kx^2
i mean the ma..
a is g
oww.. okok, yeah, i can remember it now,, gheez thanks !! ..
can i still ask one more??
A block with mass of 0.5 kg is forced against a horizontal spring of negligible mass. compressing the spring a distance of 0.20m. When released, the block moves on a horizontal tabletop for 1 meter before coming to rest. The spring constant is 100N/m. What is the coefficient of friction between the block and the tabletop?
basically all the kinetic energy of the spring is converted into heat/friction
wait. whats this --> (mu_k)
coefficient of friction
i think its just mu..
aww. okok, k stands for kinetic xDD
