What is the kinetic energy of a golf ball with a mass of 0.046 kg traveling at 15.5 m/s?

Physics
1 answer:
Serjik [45]3 years ago
3 0

Answer:

<h2>5.53 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 0.046 \times {15.5}^{2}  \\  = 0.023 \times 240.25 \\  = 5.52575

We have the final answer as

<h3>5.53 J</h3>

Hope this helps you

7. If the impact of the golf club on the ball in the previous question occurs over a time of 2 x 10 seconds, what
Kruka [31]

Answer:

3.65 x mass

Explanation:

Given parameters:

Time  = 20s

Initial velocity  = 0m/s

Final velocity  = 73m/s

Unknown:

Force the ball experience  = ?

Solution:

To solve this problem, we apply the equation from newton's second law of motion:

    F  =  m \frac{v  - u}{t}  

m is the mass

v is the final velocity

u is the initial velocity

 t is the time taken

So;

  F  = m (\frac{73 - 0}{20} )  = 3.65 x mass

How do i find stretch? The problem in questioning has already given me the elastic energy and k-value, but I have no idea how to
finlep [7]

Answer:

Stretch can be obtained using the Elastic potential energy formula.

The expression to find the stretch (x) is x=\sqrt{\frac{2\times EPE}{k}}

Explanation:

Given:

Elastic potential energy (EPE) of the spring mass system and the spring constant (k) are given.

To find: Elongation in the spring (x).

We can find the elongation or stretch of the spring using the formula for Elastic Potential Energy (EPE).

The formula to find EPE is given as:

EPE=\frac{1}{2}kx^2

Rewriting the above expression in terms of 'x', we get:

x=\sqrt{\frac{2\times EPE}{k}}

Example:

If EPE = 100 J and spring constant, k = 2 N/m.

Elongation or stretch is given as:

x=\sqrt{\frac{2\times EPE}{k}}\\\\x=\sqrt{\frac{2\times 100}{2}}\\\\x=\sqrt{100}=10\ m

Therefore, the stretch in the spring is 10 m.

So, stretch in the spring can be calculated using the formula for Elastic Potential Energy.

________ is the name for when a director decides where and when performers move and position themselves on the stage.
Maurinko [17]

Answer:

Blocking/staging

Explanation:

Blocking/staging is the name for when a director decides where and when performers move and position themselves on the stage.

Moreover, Blocking a dream sequence is merely "working on the details of an actor's movements with regard to the camera." We can also reckon of blocking as the dance routines of a dance or a ballet: all the components on the set must move in perfect sync with one another (performers, extras, automobiles, crew, machinery).
