need help from this question

i need the final answer quickk pls

Context The needle of a sewing machine makes a repetitive up and down motion which is described by the equation y(t)=Acos(wt) To choose the settings of the device that will ensure that the needle successfully pierces the textile, you are asked to model the speed in ? of the needle as a function of time. Constraints and information The parameter A represents the range of motion (in m);The parameter w represents the angular frequency. It tells us about the number of back and forth movements that the needle makes per second;The parameter w is given in rad/s, so your calculator absolutely must be in radians mode to do the calculations in this problem;Modelization Establish the model for the y velocity of the needle as a function of time and the parameters A and w. Then test your model by calculating the speed in y of the needle at the moment and with the given parameters: Moment: 4.1 s Amplitude: 0.012 m Angular frequency: 17.9 rad/s

I want clear answer to get to the answer of that question

Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires. Q1. I have good information that in Fast 29, Dominic Toretto (Vin Diesel) will need to refill a tire quickly during a dramatic moment. For this reason, he has a 3.00 L tank of compressed air that is under 2.7892*103 mmHg and is kept cool in dry ice at -35.0 °C. When Dom hooks his compressed air up to his completely empty 10.50 L tire at 39.2 °C and lets it run, what will his final tire pressure be, in atm? Assume all the air is transferred into the tire. Is his tire pressure above the 2.31 atm that he needs to save the planet/his family/his crew? Q2. Your car tire pressure sensor looks to see when your tire pressure…

Required information The cutaway of the gun barrel shows a projectile moving through the barrel. The projectile's exit speed is vs = 1675 m/s (relative to the barrel), the projectile's mass is 18.5 kg, the length of the barrel is L = 4.4 m, the acceleration of the projectile down the gun barrel is constant, and Ⓡ is increasing at a constant rate of 0.18 rad/s. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. L Determine the pressure force acting on the back of the projectile. It is given that = 20°. (Round the final answer to four decimal places.) The pressure force on the projectile is 31.8882 × 106 N.

2.1.28. [Level 2] In the year 2137 a hovering spacecraft releases a probe in the atmosphere far above the surface of New Earth, a planet orbiting Alpha Proximi. The gravita- tional acceleration g1 is constant and equal to 7.5 m/s?. How far will the probe have traveled when it has reached 98% of its terminal speed? The probe's speed is governed by ÿ = -g1 + cy where y is the probe's position above the planet's surface (expressed in m). c = 1.2 × 10-4 m-1.

An 8 bits absolute binary encoder is used to measure the distance traveled by the material in the conveyor. It is connected in the shaft (d=40cm) where the belt rotates. In the initial location of material the encoder reading is 11010110 as the conveyor rotates, the encoder created 2 complete rotation clockwise and end up with the value of 10001101. What is the distance travelled by the material.

You are part of a car accident investigative team, looking into a case where a car drove off a bridge. You are using the lab projectile launcher to simulate the accident and to test your mathematical model (an equation that applies to the situation) before you apply the model to the accident data. We are assuming we can treat the car as a projectile.

Two small objects of mass mo and a rotating platform of radius R and rotational inertia I, about its center compose a single system. Students use the system to conduct two experiments. The objects are assumed to be point masses. Experiment 1 mo R mo Fo Figure 1 Each object of mass mo is placed a distance rị away from the center of the platform such that both masses are on opposite sides of the platform. A constant tangential force Fo is applied to the edge of the platform for a time Ato, as shown in Figure 1. The system is initially at rest. Experiment 2 R r2 r2 Fo Figure 2 Each object of mass mo is placed a distance r2 away from the center of the platform such that both masses are on opposite sides of the platform. Distance r2 < rị .A constant tangential force Fo is applied to the edge of the platform for a time Ato , as shown in Figure 2. The system is initially at rest.
