# Can someone provide the solutions to these questions asked in my exam in my high school [closed]

In the arrangement shown in the figure, initially the block of mass 'm1' is in limiting equilibrium. The coefficient of friction between the block of mass m1, and floor is 'u' Now the particle of mass m2 is given a horizontal velocity 'V0'. The initial distance of the block of mass m2 from the pulley is 'L'. The masses of pulley and threads are negligible. Choose the correct option(s):

A) Acceleration of m1 just after the velocity given is (u/(1 + u)) * (v0^2)/L

B) Acceleration of m1 just after the velocity given is (u/(1 + u)) * (v0^ 2)/(2L)

C) Radius of curvature of path of m2 just after the velocity given is L(1 + u)

D) Radius of curvature of path of m2 just after the velocity given is 2L(1+ u)

• Hint: the last two are dimensionally inconsistent; use the case $u=1$ to choose between the first two.

• Thanks, just corrected it. If possible can you provide the rough idea of how to proceed Sep 19 at 16:22
• Are you asking for help with your exam? If so, that’s cheating. (At least it was when I took exams.) If the exam is over, you should be able to ask the teacher. Sep 19 at 23:27
• No the exam was weeks ago, and am not in the place to ask my teacher for help. Sep 20 at 4:29
