Two objects A and B flies towards each other. When the distance between them is 1.2km their velocities  and acceleration are as follows: VA=40 m/s, VB=15 m/s, aA= -0.5 m/s^2 and aB= 1.36 m/s^2. A Third object  left object A and moves toward object B with velocity of 50m/s. Upon reaching B it then flies back to A  and so on until A and B meets. What is the total distance traveled by the third object?

Two cars are driving, car 1 has initial position -3500m, initial velocity -55m/s and acceleration +1.25m/s2, car 2 has initial position +4100m, initial velocity -35 m/s and acceleration +0.75m/s2;   a) How much time until they collide? b) What is the x location where they collide, and the final velocity of each car?

You decide to relax & play some basketball (m = 413g). You throw the ball from an initial height of 1.13m (represented by hA on the diagram). When it hits the net (which is 2.20m high), it has a speed of 7m/s. How fast was the ball going when it left your hand? hA = height of throw = 1.13m hB = height of net = 2.20m %3D

An object A moves along the x-axis according to the equation: x(t) = 3.5t2+1.7t+14.0 where x is in meters while t is in seconds, the other object B moves along the x-axis with constant speed 10.0 m/s. At what time  the object A has the same instantaneous velocity  as the object B? State your answer in seconds to the nearest 0.01s.

Suppose it takes you 2 minutes and 13 seconds to swim 8 lengths of a 25.0 meter swimming pool (out and back 4 times, ending up where you started). What is your average velocity during this time interval? What is your average speed during this time interval? options: 0 m/s 3.0 m/s 1.5 m/s

An electron is moving in a straight line with a initial speed of3E5 m/s. It then undergoes an accelerates 8E14m/ s. How long will it take to reach a speed of 5.4E 5m/s?

I had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?

You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.

The x component of the velocity of an object moving along the x axis is given as vy = 4t – 3t where vy is in meters per sec and t in seconds. The x component of its average velocity over the interval of time from t =0 to t= 2 sec is: O -2m/s O 2 m/s O -4m/s

A particle is initially traveling east at 5 m/s , then it begins to have an acceleration of 10 m/s2 in the north direction. What can you say about its velocity after a long period of time.
