1) If the eastward component of a vecto of the second vector and their south say about the two vectors? 2. If A and B are non-zero vectors for w 3. What is 0.578/0.65 to the proper nur 4. The difference between 125.5 and 12 significant figures is 9. What is the instantaneous velocity and acceleration of the object x-a3-bt for a-3.0 m/s3.b = 2 ms. t=25s, x andare in SI units 10. What is the magnitude of the average acceleration of a skier who, starts from rest reaches a speed of 18.0m's when going down a slope for 4.0 ? 11. A foul ball is hit straight up into the air with a speed of 50.0 ms. The time required for the ball to rise to its maximum height is g -9.8 m/s2). 12. How do the x and y components of the velocity vector of the ball compare at the points and C? The x components are the same, they component at C is zero m/s. 13. If an object travels at a constant speed in a circular path, the acceleration of the object is 14. For a particle moving at constant speed in a circular path, the direction of acceleration is 15. A plane has an eastward heading at a speed 170m's relative to the air A 25 m/s wind is blowing southward while the plane is flying Calculate the velocity of the plane relative to the ground
