A train normally travels with a uniform speed of 72 km / h on a long stretch of flat, straight track. On a certain day, the train must make a 2.0 minute stop at a station on this track. If the train decelerates with a uniform rate of 1.0 m/s^ 2 and after stopping, it accelerates with a rate of 0.50 m/s^ 2. How much time will it have lost by stopping at the station?
The velocity function of a particle moving along a horizontal line is given by v(t) = ln 2 * 23t , where t ≥ 0 is in seconds. The particle is initially 2/3 units to the left of the origin. Find the position of the particle when the acceleration is equal to 6(ln 2)2 .
How far from the origin has the particle gone after 0.11 minutes if Vx = 3m/s , Vy = 2 m/s and Vz = 3.31 m/s. Assume that the particle is moving at a constant rate.
The British Queen Elizabeth-class battleship HMS Warspite achieved the longest naval gunnery hit from a moving ship to a moving target in history, hitting the Italian battleship Guilio Cesare in the Battle of Taranto. According to known data, the range was 24000 meters, and that the British 15-inch Mk I naval gun has a maximum muzzle velocity of 800 meters per second. Due to movement, a headwind was against the British battleship, forcing its shells to decelerate by approximately 0.5 meters per second squared. Find the firing angle of the Warspite upon hitting Guilio Cesare. Find the impact velocity of the 15-inch naval cannon's shell.
I am having trouble with a 3d motion problem. The problem is as follosw, "At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of i = (3.00 i - 2.00 j) m/s and is at the origin. At t = 2.00 s, the particle's velocity is = (7.00 i + 8.20 j) m/s. (Use the following as necessary: t. Round your coefficients to two decimal places.)" The problem asks me to find acceleration of the particle at any time t and to find its coordinates at any time t. Thanks for the help
1) If the displacement of a particle is decreasing at a constant rate its velocity is constant. True or False 2) Knowing the position and velocity of a particle allows its future position to be predicted even if its acceleration is unknown. True or False 3) Average acceleration and instantaneous acceleration are always the same. True or False 4) Instantaneous velocity is the derivative of the displacement time function. True or False 5) The slope of the velocity-time graph is the instantaneous acceleration. True or False
A boat is cruising in a straight line at a constant speed of 2.5 m/sm/s when it is shifted into neutral. After coasting 11 mm the engine is engaged again, and the boat resumes cruising at the reduced constant speed of 1.5 m/s. Assuming constant acceleration while coasting, how much time did it take for the boat to coast the 11 mm?

In the particle under constant acceleration model, we identify the variables and parameters vxi, vxf, ax, t, and xf xi. Of the equations in the model. Equations 2.132.17, the first does not involve xf xi, the second and third do not contain ax, the fourth omits vxf, and the last leaves out t. So, to complete the set, there should be an equation not involving vxi. Derive it from the others.
A blue car of length 4.52 m is moving north on a roadway (hat intersects another perpendicular roadway (Fig. P2.81, page 58). The width of the intersection from near edge to far edge is 28.0 m. The blue car has a constant acceleration of magnitude 2.10 m/s2 directed south.

Two particles are currently in motion along parallel, straight paths in the positive x-direction, between two timing gates that are spaced at a distance d from each other. They both pass the first timing gate with a “flying start”, at t0 = 0, and they move as follows: - Particle A is moving with a constant velocity, vA - Particle B passes the first timing gate with a momentary velocity vB0 > 0, and a constant acceleration of aB = const. - After some time t1, both particles meet again at the second timing gate! a) Write the motion path equations x(t) for each particle in algebraic form Solve the following questions numerically for these parameters: d = 600m, t1 = 100s, vB0 = 15m/s b) What is the constant velocity for particle A? c) What is the constant acceleration for particle B? d) At what time does particle B come to a stop? e) What is the velocity for particle B at the second gate at the time t1? f) What is the total distance travelled for particle B? g) What is the average…
