What is the momentum of a 0.145 kg baseball traveling at 40.0 m/s

dimulka [17.4K]

Answer: 5.8 kg m/s

Identify the given information.
m = 0.145 kg
v = 40.0 m/s

Choose which formula you should use. In this case, you are finding momentum.
p = mv, where p is momentum.

Substitute and solve.
p = 0.145 kg x 40.0 m/s
p = 5.8 kg m/s

What is the net torque on the square plate, with sides 0.2 m, from each of the three forces? F1=18 N, F2=26 N, and F3=14 N. Use

marshall27 [118]

Answer:

The net torque on the square plate is 2.72 N-m.

Explanation:

Given that,

Side = 0.2 m

Force $F_{1}=18\ N$

Force $F_{2}=26\ N$

Force $F_{3}=14\ N$

We need to calculate the torque due to force F₁

Using formula of torque

$\tau_{1}=-F_{1}d_{1}$

$\tau_{1}=-F_{1}\times\dfrac{a}{2}$

Put the value into the formula

$\tau_{1}=-18\times\dfrac{0.2}{2}$

$\tau_{1}=-1.8\ N-m$

We need to calculate the torque due to force F₂

Using formula of torque

$\tau_{2}=F_{2}d_{2}$

$\tau_{2}=F_{2}\times\dfrac{a}{2}$

Put the value into the formula

$\tau_{2}=26\times\dfrac{0.2}{2}$

$\tau_{2}=2.6\ N-m$

We need to calculate the torque due to force F₃

Using formula of torque

$\tau_{3}=F_{3}d_{3}$

$\tau_{3}=(F_{3}\sin45+F_{3}\cos45)\times\dfrac{a}{2}$

Put the value into the formula

$\tau_{3}=0.1(14\sin45+14\cos45)$

$\tau_{3}=1.92\ N-m$

We need to calculate the net torque on the square plate

$\tau=\tau_{1}+\tau_{2}+\tau_{3}$

$\tau=-1.8+2.6+1.92$

$\tau=2.72\ N-m$

Hence, The net torque on the square plate is 2.72 N-m.

A singer demonstrated that she could shatter a crystal glass by singing a note with a wavelength of 0.320 meter in air at stp. w

ololo11 [35]

In order for the singer to break the glass, she should be able to mimic the frequency of the glass through the voice. Frequency is calculated by dividing the speed with the wavelength. Therefore,

Frequency = speed / wavelength
Frequency = 340.29 m/s / 0.320 m
Frequency = 1063.41 /s
