Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

2. In Lab 7 you used a ballistic pendulum to measure the speed of a ball propelled by a
projectile launcher. The ballistic pendulum can be considered a solid rod rotating around an
axis at one end, as in the diagram:
24.5 cm
mpall
Vtotal
Vpall
Mtotal
Трепd
In the lab, I measured the following initial conditions:
Mass of the ball, mpall = 10 g
Mass of the pendulum, mpend = 242 g
Length of pendulum, l = 24.5 cm
For the angle the pendulum is deflected, I found 0 = 0.17 rad and assumed the time for the
deflection is 50 ms.
Equate the expressions for the kinetic energy of the ball/pendulum combination and for the
kinetic energy of rotation to find the velocity of the ball/pendulum combination, and then use
conservation of momentum to find the initial velocity of the ball. How does the velocity compare
with what you calculated for the plastic ball shot at the high velocity setting in Lab 7?
