A nucleus Is at rest in the laboratory frame of reference. Show that if it disintegrates into two smaller nuclei the products must move in opposite, directions

Two cars are moving in the same direction with the same speed ( = 30km/hr ). They are separated by a distance of 5 km. What is the speed of a car moving in the opposite direction if it met these cars at an interval of 4 minutes?

One often comes across the following kind of statement concerning circular motion. A particle moving uniformly along a circle experiences a force directed towards the centre and an equal and opposite force directed away from the centre. The two forces together keep the particle in equilibrium. Explain, what is wrong with this statement?

On a two-lane road, car A travelling with a speed of 15ms^-1 is approached by two cars B and C moving with speed 20 ms^-1 each in opposite directions. At an instant when the distance AB is equal to AC , both being 700 m, B decides to overtake A before C does. Find the minimum acceleration required by B to avoid accident.

Two equal masses, one at rest and another moving undergo elastic QB lique collision. If one mass goes at an angle pi/3 .with its original direction of motion, what is the direction of motion of the other?

Two particles, each of mass m and speed v_3 travel in opposite directions along parallel lines separated by a distance d. Show that the vector angular momentum of the two particle system is the same whatever be the point about which the angular momentum is taken.

A stationary particle explodes into two particle of masses m1 and m2 and move in opposite directions with velocities v1 and v2.The ratio of their K.E is

Two objects, each of mass 1.5 kg, are moving in the same straight line but in opposite directions. The velocity of each object is 2.5 m s^-1 before the collision during which they stick together. What will be the velocity of the combined object after collision?

Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 m s~1 collide and rebound with the same speed. What is the impulse imparted to each ball due to the other?

A ball moving with a speed of 9m.s strikes an identical ball at rest, such that direction fo eahc ball makes an angle 30^@ with the original line. Find the speed of two ball after collision.
