Answer:
60000N
Explanation:
acceleration is change in velocity
a =(v-u)/t where a is acceleration u is initial velocity and v is final velocity
a = (0-60)/5 = -60/5= - 12m/s^2
here minus sign shows that body is decelerating and force is force of friction Now f = ma here f is force of friction m is mass and a is acceleration
f= 5000×- 12= -60000N
MINUS SIGN HERE SHOWS FORCE OF FRICTION
Hence force of friction is 60000N
Because polymers are covalently bonded material, and metals are metalicly bonded material.
Covalent bonds do not let atoms exchange electrons like metalic bonds do.
