hi, i need answer on the questions below. please provide explanation or solution if needed so i can better understand it. thank you!

30. A ladybug was seen to be jumping from one flower to another. If the initial position of the ladybug is at coordinate (2 m, 2 m, 3 m), express the displacement vector of the ladybug after reaching the second flower at (15 m, 22 m, 54 m) in I, j, k. Note: j and j are unit vectors A. 301 + 44j + 162k B. 17i + 24j + 57k C. 13i + 20j + 52k D. 7.5i + 11j + 18k E. No Answer 31. Which of the following statements is INCORRECT? a. If the speed is constant, the velocity is constant b. If the velocity is constant, the speed is constant c. If the body moves in a straight line with a constant speed, velocity is constant. d. If the speed is constant, the velocity might be constant or not depending on the direction. No Answer32. A ball is moving along a circular track. What can be said about the orientation of the velocity and acceleration vectors if the ball is speeding up? A. Oriented at an angle less than 90 degrees B. Oriented at 0 degrees C. Oriented at an angle greater than 90 degrees D. Out of phase by 180 degrees E. No Answer 33. Which of the following is true? A. Kinematics is about the geometric description of motion. B. Kinematics is about the causes of motion of objects. C. Kinematics is about the description of forces that affects motion. D. Kinematics is about the description on how velocity changes through time. E. No Answer34. A model of a helicopter rotor has four blades, each 3.40 m long from the central shaft to the blade tip. The model is rotated in a wind tunnel at 550 rev/min. What is the linear speed of the blade tip in m/s? A. 60 m/S B. 120 m/5 C. 148 m/s D. 196 m/s E. No Answer 35. Travelling with an initial speed of 70 km/hr, a car accelerates at 6000 km/h^2 along a straight road. How long will it take to reach a speed of 120 km/h? Also, what distance does the car travel during this time? A. t = 15 5; x = 578 m B. t = 30 s; x = 792 m C. t = 45 s; x = 1064 m D. t = 60 s; x = 1297 m E. No
