HELP PLS! :/

Physics
1 answer:
zlopas [31]3 years ago
7 0

Explanation:

formula: Vi = Vf - (at)

Vi: intial velocity

Vf: final velocity

a: acceleration

t: time

fill in formula with the numbers you are given

Vi= 41.6m - ((9.81 m/s^2)(1.89s))

parenthesis first according to pemdas

Vi= 41.6m - 18.54m/s

Answer: 23.06m/s

disclaimer: I havent done physics in awhile so I have no idea if this is right. just an attempt to help steer you in the right direction hopefully. good luck

Point P is on the rim of a wheel of radius 2.0 m. At time t = 0, the wheel is at rest, and P is on the x-axis. The wheel undergo
oksian1 [2.3K]

Answer:

e). a = 0.066 m/s^2

Explanation:

As we know that wheel is turned by 90 degree angle

so the angular speed of the wheel is given as

\omega_f^2 - \omega_i^2 = 2\alpha \theta

now we have

\omega_f^2 - 0 = 2(0.01)(\frac{\pi}{2})

\omega = 0.177 rad/s

now the centripetal acceleration of the point P is given as

a_c = \omega^2 R

a_c = (0.177)^2(2)

a_c = 0.063 m/s^2

tangential acceleration is given as

a_t = R\alpha

a_t = 2(0.01)

a_t = 0.02 m/s^2

now net acceleration is given as

a = \sqrt{a_t^2 + a_c^2}

a = \sqrt{0.02^2 + 0.063^2}

a = 0.066 m/s^2

The doppler effect is when objects are not moving?<br><br> True <br><br> False
SVETLANKA909090 [29]

Answer:

reviewing the statement we can say that it is FALSE

Explanation:

The Doppler effect is the change in the perceived frequency of a sound wave by the RELATIVE MOTION of the source and the observer.

This effect is very useful for finding the speed of an object.

When reviewing the statement we can say that it is FALSE

For a snowboard jumper in the air, what force or forces will be most important for modeling the motion?
Reptile [31]

Answer: Gravitational force and drag force

Explanation:

For a snowboard jumper in the air, two forces would be acting. One in the downward direction- the gravitational pull and second in the opposite direction to the motion, the drag force due to air. If the snowboard jumper jumps in the air at a certain angle with the horizontal. The forces are written as the sum of vertical and horizontal components. Hence, for the modeling the motion, gravitational force and drag force are important,
