JEE Main 2024 · 1 Feb · Shift 1 · Inelastic Collision

A simple pendulum of length 1 m1 \mathrm{~m} has a wooden bob of mass 1 kg1 \mathrm{~kg}. It is struck by a bullet of mass 10−2 kg10^{-2} \mathrm{~kg} moving with a speed of 2×102 ms−12 \times 10^2 \mathrm{~ms}^{-1}. The bullet gets embedded into the bob. The height to which the bob rises before swinging back is. (use g=10 m/s2\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2 )

  3. (C)0.30 m0.30 \mathrm{~m}
  4. (D)0.35 m0.35 \mathrm{~m}

Answer: (A)

Step-by-step solution

JEE Main 2023 · 6 Apr · Shift 2 · Coefficient of Restitution

A body is dropped on ground from a height 'h1h_{1}' and after hitting the ground, it rebounds to a height 'h2h_{2}'. If the ratio of velocities of the body just before and after hitting ground is 4 , then percentage loss in kinetic energy of the body is x4\frac{x}{4}. The value of xx is ____________.

Answer: 375
