The collar A in Fig. (a) slides along the rotating rod OB. The angular position of the rod is given by 0 = =nt2 rad, and the distance of the collar from 0 varies as R= 18t +4 m, where time tis %3D measured in seconds. Determine the velocity and acceleration vectors of the collar at t= 0.5s.
A B A gas enters a piping section AB from the left at density 1.15 kg/m³ and with speed 4 meters/sec. The pipe section has a constant diameter of 10 centimeters. While passing through AB the gas density changes to 0.95 kg/m³. Determine the speed with which the gas exits section AB in meters/sec. Assume steady flow and use the continuity equation. Your answer should include at least 2 digits after the decimal place.

We investigated a jet landing on an aircraft carrier. In a later maneuver,the jet comes in for a landing on solid ground with a speed of 95 m/s, and itsacceleration can have a maximum magnitude of 6.37 m/s2 as it comes to rest.(a) From the instant the jet touches the runway, what is the minimum time intervalneeded before it can come to rest?(b) Can this jet land on a small tropical island airport where the runway is 0.800 kmlong? Show your work using a calculation.
If you are not sure pass it. I dont want wrong answers, hand written solution is also fine but wrong answer i will report. A body of mass 5 kg is projected vertically upward with an initial velocity 17 meters per second. The gravitational constant is 9.8 m/s2. The air resistance is equal to k|v| where k is a constant. (1)Find a formula for the velocity at any time v(t) in terms of k. (2)Find the limit of this velocity for a fixed time (t0) as the air resistance coefficient k goes to zero.
A man decided to travel in a straight path from point A topoint B. Starting from rest, the man decided to accelerate at aconstant acceleration of 12960 km/h^2 until il covers 450 meters and then maintain its velocity. After traveling for 2 kilometers, the car decelerates at a rate of 2m/s^2 until it reaches it destination. How long did the driver drove his car in seconds.
Please solve this question as soon as possible, thank you.
Answer it correctly please. I
A small rocket is launched vertically from rest and it accelerates uniformly at 26 m/s² for a period of 13 s, at which point all of its fuel is used. The rocket then continues to travel freely in the vertical direction until it eventually reaches its maximum altitude, after which it falls to earth. Working to 4 significant figures, calculate for the rocket: (a) Its velocity at the instant when all of its fuel is used. m/s (b) Its altitude at the instant when all of its fuel is used. m (c) (i) The time taken for the rocket to slow from the point it runs out of fuel until it reaches maximum altitude. S (ii) The total time taken to reach its maximum altitude S (d) The maximum altitude reached m (e) Its velocity at the instant just prior to impact with the ground. m/s

A turtle crawls along a straight line, which we’llcall the x-axis with the positive direction to the right. The equationfor the turtle’s position as a function of time is x 1t2 = 50.0 cm +(2.00 cm/s)t - (0.0625 cm/s2)t2. Find the turtle’s initial velocity, initial position, and initial acceleration.
