Why is the following situation impossible? A freight train is lumbering along at a constant speed of 16.0 m/s. Behind the freight train on the same track is a passenger train traveling in the same direction at 40.0 m/s. When the front of the passenger train is 58.5 m from the back of the freight train, the engineer on the passenger train recognizes the danger and hits the brakes of his train, causing the train to move with acceleration 23.00 m/s2. Because of the engineer’s action, the trains do not collide.

Why is the following situation impossible? A freight train is lumbering along at a constant speed of 16.0 m/s. Behind the freight train on the same track is a passenger train traveling in the same direction at 40.0 m/s. When the front of the passenger train is 58.5 m from the back of the freight train, the engineer on the passenger train recognizes the danger and hits the brakes of his train, causing the train to move with acceleration 3.00 m/s2. Because of the engineers action, the trains do not collide.
A particle moves along the x axis according to the equation x = 2.00 + 3.00t 1.00t2, where x is in meters and t is in seconds. At t = 3.00 s, find (a) the position of the particle, (b) its velocity, and (c) its acceleration.
A spacecraft is traveling with a velocity of v0x = 5460 m/s along the +x direction. Two engines are turned on for a time of 854 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.20 m/s2, while the other gives it an acceleration in the +y direction of ay = 8.60 m/s2. At the end of the firing, find the following.(a) vx = m/s(b) vy = m/s
At time t=0s, an object is moving to the right with a velocity v that can be modeled by the equation v=(4.2 m/s)-(1.4 m/s2)t. At what time, if any, does the object change its direction of motion?
A cheetah is squatted 25m to the east of a vehicle. At time t = 0 the cheetah begins to run due east toward an antelope that is 55m to the east of the vehicle. During the first 2.0 s of the chase,the cheetah’s x-coordinate varies with time according to the equationx = 25m + (4.5m/s2)t2. (a) Find the cheetah’s displacement between t1= 1.5s and t2= 3.0 s. (b) Find its average velocity during that interval. (c) Find its instantaneous velocity at t= 2.5s by taking Δt = 0.15s.
Given the following acceleration function of an object moving along a line, find the position function with the given initial velocity and position. a(t)=−28; v(0)=21; s(0)=0
In reaching her destination, a backpacker walks with an average velocity of 1.17 m/s, due west. This average velocity results, because she hikes for 6.57 km with an average velocity of 2.53 m/s, due west, turns around, and hikes with an average velocity of 0.425 m/s, due east. How far east did she walk?
A body moving in the positive x-direction passes the origin at time t = 0. Between t = 0 and t = 1 second, the body has a constant speed of 14 (m/s). At t = 1 second, the body is given a constant acceleration of 5 (m/s2) in the negative x-direction. The position x of the body in meters at t = 9 seconds is
A westbound car on the PA turnpike passes the exit for the northeast extension traveling at 16.2 m/s. If the car experiences a constant eastward acceleration of 2.13 m/s2, give the car's velocity after 3.36 s. Answer in m/s, using a coordinate system in which positive is toward the east.
A child running in a field has the following position and velocity at time t=0: x = 1.5 m. v= -2.0 m. Vx =-3.5 m/s, vy = 1.0 m/s At time t = 2.5 s, it has the following position and velocitv: x = -1.0 m, y = 1.5 m 08.
