1. A projectile is launched with an initial velocity *v* at an angle θ to the horizontal. Neglecting air resistance, what is the range of the projectile?

   • (v^2 * sin(θ)) / g
   • (v^2 * sin(2θ)) / (2g)
   • (v^2 * sin(2θ)) / g
   • (2 * v^2 * sin(θ) * cos(θ)) / (g^2)
   Show answer & explanation

   Answer: C. (v^2 * sin(2θ)) / g

   The range R of a projectile is given by R = (v^2 * sin(2θ)) / g. This is derived from the equations of motion considering horizontal and vertical components of velocity and the time of flight.

2. A car of mass *m* is moving around a banked curve of radius *r* at a constant speed *v*. The angle of banking is θ. What is the optimum angle of banking (i.e., the angle at which no frictional force is required)?

   • tan⁻¹(v / (rg))
   • tan⁻¹(v² / (rg))
   • tan⁻¹((rg) / v)
   • tan⁻¹((rg) / v²)
   Show answer & explanation

   Answer: B. tan⁻¹(v² / (rg))

   The optimum angle of banking is given by tan θ = v²/rg. This is derived by considering the horizontal component of the normal reaction providing the necessary centripetal force.

3. A block of mass *m* slides down a rough inclined plane with constant velocity. The angle of inclination is θ and the coefficient of kinetic friction is μ. What is the magnitude of the frictional force acting on the block?

   • mg * sin(θ)
   • mg * cos(θ)
   • μ * mg * sin(θ)
   • μ * mg * cos(θ)
   Show answer & explanation

   Answer: A. mg * sin(θ)

   Since the block moves with constant velocity, the net force is zero. The component of weight down the plane (mg sin θ) must be equal to the frictional force. Therefore, Frictional force = mg * sin(θ).

4. A particle is executing simple harmonic motion (SHM) with amplitude A and angular frequency ω. What is the ratio of its maximum kinetic energy to its maximum potential energy?

   • ω
   • ω²
   • 1
   • A
   Show answer & explanation

   Answer: C. 1

   In SHM, the maximum kinetic energy (1/2 m v_max^2 = 1/2 m ω^2 A^2) is equal to the maximum potential energy (1/2 k A^2 = 1/2 m ω^2 A^2). Therefore, the ratio is 1.

5. A sphere of mass *m* and radius *r* rolls without slipping down an inclined plane of height *h*. What is the speed of the sphere at the bottom of the incline?

   • √(gh)
   • √(2gh)
   • √(10gh/7)
   • √(5gh/3)
   Show answer & explanation

   Answer: C. √(10gh/7)

   Using conservation of energy, mgh = 1/2 mv^2 + 1/2 Iω^2. For a sphere, I = (2/5)mr^2 and v = rω. Substituting and solving for v gives v = √(10gh/7).

6. A satellite is orbiting the Earth at a height *h* above the surface. The radius of the Earth is *R* and the acceleration due to gravity at the Earth's surface is *g*. What is the orbital speed of the satellite?

   • √(gR)
   • √(g(R+h))
   • √(gR² / (R+h))
   • √(gR²)
   Show answer & explanation

   Answer: C. √(gR² / (R+h))

   The gravitational force provides the centripetal force: GmM/(R+h)² = mv²/(R+h). Also, g = GM/R². Combining these gives v = √(gR² / (R+h)).

7. Two objects of mass *m₁* and *m₂* are moving towards each other with speeds *v₁* and *v₂* respectively. They collide head-on in a perfectly inelastic collision. What is the loss of kinetic energy in the collision?

   • 0
   • 1/2 * (m₁ * m₂ / (m₁ + m₂)) * (v₁ + v₂)²
   • 1/2 * (m₁ * m₂ / (m₁ + m₂)) * (v₁ - v₂)²
   • 1/2 * (m₁ + m₂) * (v₁ - v₂)²
   Show answer & explanation

   Answer: B. 1/2 * (m₁ * m₂ / (m₁ + m₂)) * (v₁ + v₂)²

   In a perfectly inelastic collision, the objects stick together. Calculate the final velocity using conservation of momentum. The loss in KE is the initial KE minus the final KE, which simplifies to 1/2 * (m₁ * m₂ / (m₁ + m₂)) * (v₁ + v₂)².

8. A uniform rod of length *L* and mass *M* is pivoted at one end. What is the moment of inertia of the rod about the pivot point?

   • 1/12 * ML²
   • 1/3 * ML²
   • 1/2 * ML²
   • ML²
   Show answer & explanation

   Answer: B. 1/3 * ML²

   The moment of inertia of a uniform rod about its center is 1/12 ML². Using the parallel axis theorem, the moment of inertia about one end is I = 1/12 ML² + M(L/2)² = 1/3 ML².
