Impulse Calculation:
- Given initial speed of the ball, v = 54 km/hr = 15 m/s
- Mass of the ball, m = 0.15 kg
- The angle of deflection, θ = 90°
Impulse Formula:
Impulse = Change in momentum
Change in Momentum Formula:
Change in momentum = Final momentum - Initial momentum
Initial Momentum Calculation:
Initial momentum = mass x initial velocity
Initial momentum = 0.15 kg x 15 m/s
Final Momentum Calculation:
Final momentum will be in a direction perpendicular to the initial direction, so the x-component of the final momentum will be:
Final momentum = mass x final velocity x cos(90°)
Final momentum = 0.15 kg x 15 m/s x cos(90°)
Impulse Calculation:
Impulse = Final momentum - Initial momentum
Final Calculation:
Calculate the final momentum using the formula above and subtract the initial momentum from it to find the impulse imparted to the ball.
