Short tricks for speed

  • Elastic and inelastic collisions in one and two dimensions focus drill

    Solve 15 mixed MCQs for Elastic and inelastic collisions in one and two dimensions, review every explanation, and note formulas you hesitated on.

  • Dimensional check first

    Before solving, verify each term has consistent SI dimensions — eliminates wrong options quickly in JEE MCQs.

  • Limiting cases

    Substitute extreme values (t→0, m→∞, θ→0) to sanity-check your final expression.

Q1PhysicsUnit 4: Work, Energy and Power
A cricket ball of mass 150g150 g moving with a speed of 126km/h126 k m / h hits at the middle of the bat, held firmly at its position by the batsman. The ball moves straight back to the bowler after hitting the bat. Assuming that collision between ball and bat is completely elastic and the two remain in constant for 0.001s,0.001 s, the force that the batsman had to apply to hold the bat firmly at its place would be:
Q2PhysicsUnit 4: Work, Energy and Power
Assertion (A) : The value of coefficient of restitution is independent of the masses and velocities of the colliding bodies but depends on their materials. Reason (R) : Coefficient of restitution is the ratio of the relative velocity of separation or the relative velocity of approach
