Two rockets are launched at a fireworks display. Rocket A is launched with an initial velocity v0 = 100 m/s and rocket B is launched t1 seconds later with the same initial velocity. The two rockets are timed to explode simultaneously at a height of 500 m as A is falling and B is rising. Assume a constant acceleration g = 9.81 m/s2 Determine the time t1. The time t1 is ____s.

An object moves along a straight line and experiences a constant acceleration of +1.36 cm/s2. At t = 4.6 s, its velocity is -3.41 cm/s. Express your answers in cm/s. What was the object’s velocity at t = 1.86 s?

The velocity of an object as a function of time is given by  v=3t2+5t-12 m/s, where t is in seconds. If the object has a position x = 8.00 m at t = 2.00 s, what is the position of the object at time t = 5.00 s?

I have no clue why this problem is being rejected. I have submitted similar problems and have been answered. Can I please get some help with this. Thank you!

During 9.67 s, a motorcyclist changes his velocity from v1,x = -39.1 m/s and v1,y = 13.7 m/s to v2,x = -23.7 m/s and v2.y = 29.9 m/s. Find the components of the motorcycle's average acceleration during this process, a,v,x and av.y. Aav,x m/s? dav,y m/s? II

3. A ball is thrown upwards at 13.0 m/s toward the ceiling located 6 m above the point where you release the ball. Air resistance is negligible. Objects falling near the earth's surface with no forces acting except gravity have a downwards acceleration of magnitude g. For this problem use g = 10 m/s². Write any equation you use in symbolic form before substituting in numbers. Make a labeled picture with symbols and all relevant values. Put a coordinate system on the a. picture by indicating the location of the origin and position direction. b. Find the time taken to reach the ceiling. Find the velocity just before the ball touches the ceiling. C.

A rabbit is moving in the negative x-direction at 1.50 m/s when it spots a predator and accelerates to a velocity of 12.7 m/s along the positive y-axis, all in 1.80 s. Determine the x-component and the y-component of the rabbit's acceleration. (Enter your answers in m/s2. Indicate the direction with the signs of your answers.)

What is E and F?? Please help!

An object, at time equal zero, has a velocity of 2.0 m/s and constant acceleration of 3.08 m/s². How far does it travel in 8 seconds? Do not write the units in your answer, but your answer should be in meters.

4. A robotic vehicle is exploring the surface of Mars.
