Q10. A \( 0.25 \, \text{kg} \) ball moving at \( 18 \, \text{m/s} \) at \( 53^\circ \) to a wall rebounds at the same speed and angle. What is the impulse perpendicular to the wall? (Take \( \sin 53^\circ = 0.8 \), \( \cos 53^\circ = 0.6 \))

Q11. A \( 8.4 \, \text{kg} \) block on a horizontal surface (\( \mu_k = 0.25 \)) is pulled by a \( 6.4 \, \text{kg} \) mass over a pulley. A \( 19 \, \text{N} \) force opposes the \( 8.4 \, \text{kg} \) block. What is the tension? (Take \( g = 10 \, \text{m/s}^2 \))

Q12. A \( 1 \, \text{kg} \) stone in a vertical circle of radius \( 4 \, \text{m} \) has a speed of \( 20 \, \text{m/s} \) at the bottom. A tangential force of \( 4 \, \text{N} \) acts downward from bottom to top. What is the tension at the top? (Take \( g = 10 \, \text{m/s}^2 \))

Q13. A \( 0.38 \, \text{kg} \) stone in a vertical circle of radius \( 1.9 \, \text{m} \) has a tension of \( 28 \, \text{N} \) at the bottom. What is the tension at the top? (Take \( g = 10 \, \text{m/s}^2 \))

Q14. A \( 0.2 \, \text{kg} \) ball moving at \( 25 \, \text{m/s} \) at \( 53^\circ \) to a wall rebounds elastically at \( 37^\circ \) with speed \( 20 \, \text{m/s} \). What is the impulse magnitude? (Take \( \sin 53^\circ = 0.8 \), \( \cos 53^\circ = 0.6 \), \( \sin 37^\circ = 0.6 \), \( \cos 37^\circ = 0.8 \))
