→XCIO D Question 11 7.5 pts An object moves in the x direction only under a constant acceleration. It's acceleration is 3 m/s in the *x direction. It is originally moving at 14 m/s in the direction. How long does it take in seconds, to travel a displacement of 22 m in the ex direction? Hint: Find the velocity at this displacement similar to the last question, first. Question 12 7.5 pts Car 1 is at rest at a traffic...
In the figure, particle A moves along the line y = 33 m with a constant velocity v of magnitude 2.7 m/s and directed parallel to the x axis. At the instant particle A passes the y axis, particle B leaves the origin with zero initial speed and constant acceleration ã of magnitude 0.46 m/s2. What angle θ between a and the positive direction of the y axis would result in a collision?
A motorist traveling with a constant speed of 15m/s passes a school-crossing corner, where the speed limit is 10m/s. Just as the motorist passes, a police officer on a motorcycle at the corner starts off in pursuit with constant acceleration of 3m/s^2. (a)How much time elapses before the police catches up the motorist? (b)What is the officer's speed limit at that point? (c)What is the total distance each vehicle has traveled at that point?
an object moves with a constant speed in the x-direction,but in the y-direction it is subject to an acceleration that increases linearly with time : a(t)=bt,where b is a constant. derive an equation giving the object's trajectory in this situation.
2. A 3.0 kg object moves in the +x direction with a speed of 5.0 m/s. A 8.0 kg object moves in the -x direction with a speed of 2.5 m/s. What is the momentum of this two-particle system? Assume one-dimensional motion, i.e., all vectors and movements occur along a line.
An object moves with a constant speed of 30 m/s on a circular track of a radius of 5 m. What is the magnitude of the acceleration of the object?
