Answer:
Graphing the momentum against the change in moment yields a linear relationship.
Explanation:
This is an impulse experiment,
I = ∫ F .dt
where the force and time of the collision are measured, therefore if we assume an average force the integral reduces to
I = F t
Furthermore, the momentum is equal to the change in moment of the ball, this change in moment can be found using the energy relations measuring the height of the ball and calculating its speed, in the two intervals for the descent and for the exit, possibly the heights are different so the moment change is different from zero.
Starting point. Higher
Em₀ = U = mgh
Lower end point, just before hitting the scale
= K = ½ m v²
in the path in the air there is no friction
Em₀ = Em_{f}
m g h = ½ m v²
v =
this height is different for the descent and ascent of the ball, so we have two moments
Δp = - p₀
Δp = m (v_{f} -v₀)
therefore we have the relationship
I = Δp
Graphing the momentum against the change in moment yields a linear relationship.
Through what angle does it turn during that time interval if the angular acceleration is constant: 32.0rad.
<h3>What is
angular acceleration?</h3>
- Angular acceleration is the term used to describe the temporal pace at which angular velocity varies. Radians per second is the accepted unit of measurement. Consequently, = d d t. Angular acceleration is also known as rotational acceleration.
- Angular acceleration can be calculated by dividing the angular velocity by the acceleration duration. (t). Use pi instead, or the drive speed (n) divided by the acceleration time (t) multiplied by 30. The usual SI unit for the rotational acceleration that results from this equation is radians per second squared (Rad/sec2).
Through what angle does it turn during that time interval if the angular acceleration is constant:
v(initial) = 4rad/s
v(final) = 12
t = 4 sec
a = ?
v(final) = v(initial) + at
12 = 4 + a(4)
a = 2 rad/sec2
s = ?
v(initial) = 4rad/s
v(final) = 12
a = 2rad/sec2
144 = 16 + 4s
s = 32 rads
d) 32.0rad.
