Answer:

- Turning a doorknob

- Swimming

- Hitting a tennis ball

Explanation:

Kinetic energy is the form of energy that an object or a particle has due to its motion (horizontal or vertical). An object gains kinetic energy when work is performed on it by putting a net force. This makes the object to speed up and acquire kinetic energy. Any object or particle that is moving is using kinetic energy

What total distance will a sound wave travel in air in 3.00 seconds at stp?
dimaraw [331]
At stp conditions (T=0^{\circ}C), the speed of sound is
v=331.2 m/s
The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:
S=vt
where S is the distance covered by the sound wave in a time t. In our problem, t=3.00 s, therefore the distance covered by the sound wave is
S=vt=(331.2 m/s)(3.00 s)=993.6 m

A 15kg projectile is moving with a velocity of 25m/s calculate its momentum
aliina [53]

The momentum of an object is given by:

p = mv

m is the object's mass and v is its velocity.

Given values:

m = 15kg

v = 25m/s

Plug in the values and solve for p:

p = 15*25

p = 375kg×m/s
