If a cyclist is going around a curve at constant speed, is he accelerating? If so, what is the direction of his acceleration, and how the direction is related to velocity? Explain using a graph for full credit.

A ball is thrown up and it takes 7.00 seconds to reach maximum height. Show the equation that you. a) How fast was it going when I threw it?     b) How high up did it go?         d) What was the acceleration of the ball going up? Give both magnitude and direction (up or down). Explain.         e) What was the acceleration of the ball going down? Give both magnitude and direction (up or down). Explain.         f) When was the ball speeding up and when was it slowing down? Explain.

Asking for help on 9, 10, and 11 if possible ?

1. A person kicks a ball horizontally off of a cliff 8.3 m high and it lands 22 m away on the beach. a) Sketch the situation here with labeled events b) How long does the ball take to land? c) What was the initial velocity of the ball? d) How would the time change for the ball to hit the beach if the person hit it really hard? How about if they just let it drop? Explain your answer with sketches and words. hit horizontally dropped hit harder horizontally

1. Draw a qualitative motion diagram (including both velocity and acceleration vectors) for the following objects in the following situations: Be sure to show the vector subtraction that supports how you got your acceleration vectors. a) Viewed from above, a car traveling around a traffic circle having radius R at constant speed. b) A person in a perfectly circular roller coaster loop-de loop having radius R. (Note: higher speed at the bottom of the loop than the top)

Pls solve this question quickly and 100% correct. Also could you do it handwritten for me to better understand thank you. A small airplane starts flying at a constant speed of 281 km/h on a heading of N79W. A 68 km/h wind is blowing from N13E. Determine the ground velocity of the airplane. Give direction as a quadrant bearing. Include diagram showing the vector addition with your solution.

In the pulley shown, cylinder "A" has a downward velocity of 0.3 m/s. a) Write the displacement, velocity and acceleration dependent motion equations. b) Determine the velocity of “B" including units and direction c) Determine the velocity d) Determine the velocity of VA/B including units and direction VB/A including units and direction Ув

I know the answer is c but can you please explain why

A coin that is tossed straight up into the air. After it is released, it moves upward, reaches its highest point and falls back down again. Use one of the following choices (A through G) to indicate the acceleration of the coin during each of the stages of the coin's motion described below. Take up to be the positive direction. Answer choice J if you think that none is correct. A. The acceleration is in the negative direction and constant. B. The acceleration is in the negative direction and increasing. C. The acceleration is in the negative direction and decreasing. D. The acceleration is zero. E. The acceleration is in the positive direction and constant. F. The acceleration is in the positive direction and increasing. G. The acceleration is in the positive direction and decreasing. The coin is mo downward. OE OF OJ O C O A OD OG O B

Suppose a projectile is fired with initial speed v, and angle e above the horizontal. a) Understand and plan. Draw a picture, establish a coordinate system for this problem and label your diagram. Make a table of known/given information and unknown/wanted information (this may involve reading the rest of the problem before starting). b) Using Kinematics, derive a symbolic expression for the maximum height reached by the projectile. Check the physical units of your expression. c) Using Kinematics, derive a symbolic expression for the total time the projectile is in the air. Check the physical units of your expression. d) Using Kinematics, derive an expression for the magnitude and direction angle of the projectiles velocity a time t after the object is fired. Check the physical units of your expression. e) Suppose that the projectile is fired with an initial speed of v, = 46.6 m/s and 0 = 42.2°, what is the magnitude and direction angle of the projectile's velocity t = 1.50 s after…
