The masses of two balls are in the ratio of 2 : 1 and their respective velocities are in the ratio of 1 : 2 but in opposite direction before impact. If the coefficient of restitution is ½, the velocities of separation of the balls will be equal to Half the original velocity in the opposite direction Half the original velocity in the same direction Original velocity in the same direction Original velocity in the opposite direction TRUE ANSWER : ? YOUR ANSWER : ?
A body A of mass 6.6 kg which is lying on a horizontal platform 4.5 m from its edge is connected to the end of a light string whose other end is supporting a body of mass 3.2 kg as shown in below figure. If the friction between the platform and the body A is 1/3, the acceleration is 1.25 m/sec² 0.5 m/sec² 1.00 m/sec² 0.75 m/sec² TRUE ANSWER : ? YOUR ANSWER : ?
If two bodies of masses M1 and M2(M1 > M2) are connected by alight inextensible string passing over a smooth pulley, the tension in the string, will be given by T = g(M2 - M1)/(M1 + M2) T = g(M2 + M1)/(M2 - M1) T = g(M1 - M2)/(M1 + M2) T = g(M1 + M2)/(M1 × M2) TRUE ANSWER : ? YOUR ANSWER : ?
A stone was thrown vertically upwards from the ground with a velocity of 50 m/sec. After 5 seconds another stone was thrown vertically upwards from the same place. If both the stones strike the ground at the same time, then the velocity with which the second stone was thrown should be (Assume g = 10 m/sec²) 15 m/sec 25 m/sec 50 m/sec 40 m/sec TRUE ANSWER : ?
