Explain the difference between mass and weight

Answers

Answer 1
Answer: Mass is the amount of matter in an object, and can't change unless you take a part off or add something to the object.

Weight is the amount an object weighs and can vary for multiple reasons. Such as going to the moon will change your weight, but not your mass.
Answer 2
Answer: Mass is the size of an object and Weight is the amount of gravity forced upon an object.

A particle leaves the origin with an initial velocity of 4.90 m/s in the x direction, and moves with constant acceleration ax = -1.50 m/s^2 and ay = 3.00 m/s^2. How far does the particle move in the x direction before turning around?

Answers

Answer:

it will move by d = 8.00 m in x direction before it will turn back

Explanation:

Here the initial velocity of particle is along +x direction

it is given as

now its acceleration is given as

now when it turns back then the velocity in x direction will become zero

so we will say

so it will move by d = 8.00 m in x direction before it will turn back

A woman stands at rest in front of a large, smooth wall. She holds a vibrating tuning fork of frequency Initial: fo directly in front of her (between her and the wall). (a) The woman now runs toward the wall with speed Pw, She detects beats due to the interference between the sound waves reaching her directly from the fork

Note: If the beat frequency is too large, the woman may have to use some instrumentation other than her e reaching her after being reflected from the wall. How many beats per second will she detect?

Answers

Answer:

(a)

(b)

Explanation:

(a) In the given problem, the turning fork has a frequency of . Then, a woman runs toward the wall with a speed of . From the principle of light reflection, the reflection of the sound from the fork reach the woman at a speed of v. Thus, the beat frequency is:

(b) In this part, the woman moves away from the water which is in contrast to part (a). Thus the beat frequency is:

A skateboarder is attempting to make a circular arc of radius r = 11 m in a parking lot. The total mass of the skateboard and skateboarder is m = 87 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is μs = 0.62 . (a) What is the maximum speed, in meters per second, he can travel through the arc without slipping?

Answers

The maximum speed that he can travel through the arc without slipping is mathematically given as

v = 9.93m/s

The maximum speed

Question Parameters:

Generally the equation for the Maximum velocity   is mathematically given as

Therefore

v = 9.93m/s

Therefore, the maximum speed that he can travel through the arc without slipping is

v = 9.93m/s

Answer:

V = 8.26 m/s

Explanation:

The sum of forces on the centripetal-axis is:

Maximum speed happens when friction force is maximum, so:

V = 8.26 m/s
