How can i calculate tangential acceleration

Physics
1 answer:
dolphi86 [110]4 years ago
5 0
Becuase the frisbee is spinning at a CONSTANT RATE, the radial acceleration is zero. when radial acceleration is zero, tangential acceleration is zero too, according to the equation Acceleration (tangential) = Acceleration (radial) times radius

the potential energy of a 40kg cannon ball is 14000j. How high was the cannon ball to have this much potential energy?
noname [10]
We will use the formula p = mgh p is potential energy. m is mass of object in kg g is acceleration due to gravity (9.8m/s²) h is height of the objects displacement in meters. p = mgh → mgh = p → h = p / mg p is 14000j, m is 40kg and g is 9.8 m/s² h = 14000 / 40 × 9.8 → h = 1400 / 392 → h = 35.7 Therefore , the cannonball was 35.7 meters high .

A wave traveling at 230 m/sec has a wavelength of 2.1 meters. What is the frequency of this wave?
Galina-37 [17]

Answer:

<h2>109.52 Hz</h2>

Explanation:

The frequency of the wave when given it's velocity and wavelength only can be found by using the formula

f =  \frac{c}{ \lambda}  \\

where

c is the velocity of the wave in m/s

\lambda is the wavelength in meters

From the question we have

c = 230 m/s

\lambda = 2.1 m

f =  \frac{230}{2.1}  = 109.523809... \\

We have the final answer as

<h3>109.52 Hz</h3>

Hope this helps you

a 10. kg ball thrown into the air. it is going 3.0 m/s when thrown. how much potential energy will it have at the top?
Sever21 [200]

Answer:

45 j

Explanation:

At the top, the KE will have been converted to PE

KE = 1/2 mv^2 =PEat-top = 1/2 10 *3^9 = 45 j
