An object is originally moving at 3.5 m/s in the negative x direction with a constant acceleration of 2.4 m/s2 in the negative x direction for 5.1 seconds. Then (immediately) a constant acceleration is applied to in the positive x direction. After some time, the average velocity for the entire trip is 0 m/s., and at that time, the object is moving at 61.2 m/s in the positive x direction. How long was the acceleration applied in the positive x...
1. A car moves with a constant acceleration of 12.0 m/s² in the positive x-direction. After moving 355 m, its speed is now 175.0 m/s. What was the initial speed of the car? How long did it take the car to move 355 m? 2. A projectile is fired at an angle of 60.0° above the horizontal with an initial speed of 45.0 m/s. How fast is the ball moving at the top of its trajectory?
An object starts from rest at time t= 0.00s and moves in the +x direction with constant acceleration . The object travels 9.00 m from time t = 1.00 s to time I = 2.00 s. What is the acceleration of the object?
6) An object is originally moving and a constant acceleration of 8 m/s2 is applied to it +x direction which causes it stop after 2.0 seconds. What was the magnitude of the initial velocity in m/s?
An object starts from rest and accelerated uniformly (constant acceleration). If it moves 3.0 m during the first second, then, during the first 5.00 seconds, it will move: A) 15m B) 45m C) 75m D) 225m E) 1.0m Equations to choose from: x=xo+Vof +1/2at2 V=vo+at V2=Vo2+2a(x-xo)
An object is initially traveling in the +x direction at 15 m/s. A constant acceleration of 6.7 m/s2 is applied in the -x direction. What is the displacement it travels, in meters, before it stops? If in the negative x direction, indicate so with a negative sign.
1. An object is originally moving in the +x direction at 16 m/s and a constant acceleration is applied to it. When it is at a displacement of 7 meters in the +x direction it is moving in the -x direction at 6 m/s. What is the acceleration of the object in m/s2? If in the -x direction, include a negative sign. 2. An object travels in the +x direction for 6 meters for 3.4 seconds and then, immediately, changes...

Can the velocity of an object stop and reverse direction when its acceleration is constant? Explain with 100 words or less
An object moves in one dimensional motion with constant acceleration a = 5.9 m/s2. At time t = 0 s, the object is at x0 = 4.1 m and has an initial velocity of v0 = 4.4 m/s. How far will the object move before it achieves a velocity of v = 8.5 m/s? Your answer should be accurate to the nearest 0.1 m.
