Three blocks of masses m_1 , m_2 and m_3 are connected by massless strings on a frictionless table.They are pulled with a force T_3 = 40 N .If m_1 = 10 kg ,m_2 = 6 kg and m_3 = 4 kg . th tension T_2 will be : .

A mass of 2 kg is attached to the spring of spring constant 50 N m^-1 . The lock is pulled to a distance of 5 cm from its equilibrium position at x = 0 on a horizontal frictionless surface from rest at t = 0. Write the expression for tis displacement at anytime t.

Mass m_1 moves on a slope making an angle theta with the horizontal and is attached to mass m_2 by a string passing over a frictionless pulley as shown in the figre. The co-efficient of frition between m_1 and the slopping surfaace is mu . Which of the following statements are true?

Two blocks M_1 and M_2 having equal mass are free to move on a horizontal frictionless surface. M_2 is attached to a massless spring as shown in the figure. Initially M_2 is at rest and M_1 is moving towards M_2 with speed v and collides head-on with M_2
