The diagram below shows a 1.5 kilogram kitten jumping from the top of a 1.80 meter high refrigerator to a 0.90 meter highcounter.
Refrigerator
Counter
CO
The kitten's gravitational potential energy on top of the refrigerator is greater, but what is the kitten's gravitational
potential energy on top of the counter? Assume gravity as 10, if needed.

Answers

Answer:

E = 27 J

Explanation:

It is given that,

Mass of a kitten is 1.5 kg

Initially, it was at a height of 1.8 m refrigerator and finally jumps to a 0.9 m height counter.

We need to find the kitten's gravitational  potential energy on top of the counter. Potential energy is possessed due to the position of an object. It can be given by :

E=mgh

g is acceleration due to gravity

E=1.5\ kg* 10\ m/s^2* 1.8\ m\nE=27\ J

So, the kitten's gravitational  potential energy on top of the counter is 27 J.

A170 g hockey puck sliding at 25 m/s slows to a speed of 10 m/s in a distance of
7.5 m.  Determine the force of friction
causing the puck to slow.  

Answers

From 2nd Newton Law:
F=ma
m=170g=0,17kg
Acceleration using kinematic equations:
vk²=vp²+2aΔd
vp-initial velocity=25m/s
vk-ending velocity=10m/s
Δd-distance
a=( vk^(2)- vp^(2) )/(2Δd)
a=(100-625)/(2*7,5)
a=(-525)/(15)
a=-35(m)/(s)²
F=0,17kg*(-35m/s²)=-5,95N

How much work does a person do in pushing a box with a force of 10 N over a distance of 4.0 m in the direction of the force?

Answers

There's an equation that says work = force * distance * cos (theta)

Theta being the angle between the surface and the object.

So, since the direction is the same as that of the force, you can say that theta is equal to zero.

Cos (0) = 1

So, W = (10) * (4) * (1) = 40 Joules

A skateboarder on a half-pipe changes his velocity from 6.0 m/s forwards to 4.0 m/s backward in 5.0 s. What is the acceleration of the skateboarder?

Answers

the change in velocity is 10 m/s in 5 seconds.

sinces a = change in velocity/time

a= 10/5

If a wave hits a smooth surface at an angle of incidence of 40 degrees, the angle of reflection is A. 40 degrees.
B. 0 degrees.
C. 90 degrees.
D. 80 degrees.

Answers

the angle of incidence is equal to the angle of reflection. If a wave hits a smooth surface at an angle of incidence of 40 degrees then the angle of reflection is 40 degrees.

D. 80 degrees.


The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards.   

A ship needs to sail to an island that is 1,000 km south of its starting point. If the captain sails south at a steady velocity of 30 km/h for 30 hours, will the ship make it? a) Yes b) No c) Insufficient information d) Maybe

Answers

No, it will not reach its point. Here is why:

Velocity x time

30 x 30 = 900 km

900 km is not equal to 1,000 km so the ship would have to sail for another 10 hours.

Hope this helps!
