Three point particles of masses 1.0 kg, 1.5 kg and 2.5 kg are placed at three corners of a right-angle triangle of sides 4.0 cm, 3.0 cm and 5.0 cm as shown in the figure. The center of mass of the system is at a point:

An electron moving along the x-axis has a position given by $x = 20te^{-t}$ m, where $t$ is in second. How far is the electron from the origin when it momentarily stops?
A simple pendulum has a time period of 2 s on Earth's surface. What is its time period at a height equal to the Earth's radius (R)? (Acceleration due to gravity at height h is \( g_h = \frac{g}{(1 + h/R)^2} \)).
Two identical bodies of mass 1 kg each are moving towards each other with velocities of 5 m/s and 3 m/s, respectively. They collide elastically. What will be the velocity of the body initially moving at 5 m/s after the collision?
A body of mass 2 kg is moving with a velocity of 10 m/s. What is its kinetic energy?
A block of mass 5 kg is placed on a frictionless surface and a force of 20 N is applied horizontally. What is the acceleration of the block?
A body of mass 2 kg is moving with a velocity of 3 m/s. What is its kinetic energy?
Which of the following is most accurate?
A projectile projected at an angle 30^ from the horizontal has a range R. If the angle of projection at the same initial velocity is 60^, the range will be:
A block of mass M is pulled along a horizontal frictionless surface by a rope of mass M/2. If a force 2Mg is applied at one end of the rope, the force which the rope exerts on the block is:
