Two blocks of masses M and 2M are initially traveling at the same speed v but in the opposite directions. They collide and stick
Hatshy [7]

Answer:

Explanation:

Given

Two masses M and 2 M with velocity v in opposite direction

After collision they stick together

Initial momentum

P_i=Mv-2Mv

final momentum

P_f=3Mv'

Conserving momentum

P_i=P_f

-Mv=3Mv'

v'=\frac{v}{3}

i.e. system moves towards the direction of 2M mass

Initial kinetic Energy K_1=\frac{1}{2}Mv^2+\frac{1}{2}2Mv^2

K_1=\frac{3}{2}Mv^2

Final Kinetic Energy K_2=\frac{1}{2}\cdot (3M)\cdot (\frac{v}{3})^2=\frac{3}{18}Mv^2

loss of Energy=K_1-K_2

=\frac{3}{2}Mv^2-\frac{3}{18}Mv^2

=\frac{4}{3}Mv^2

USPshnik [31]

Answer:

286

Explanation:

p1v1/T1=p2v2/T2

then subtitude your values

T2=760*0.65*273/210*0.040

T2=135/8.4=16+273=289
