Hooke's law describes a certain light spring of unstretched length 34.2 cm. When one end is attached to the top of a doorframe and a 6.75 kg object is hung from the other end, the length of the spring is 40.4 cm. (a) Find its spring constant. 1.066 kN/m (b) The load and the spring are taken down. Two people pull in opposite directions on the ends of the spring with a force of 199 N. Find the length of the spring in this situation. |0.37

hey could you please solve this question 100% correct with no mistakes. also could you solve it handwritten for me to better understand.

detail answer

12) PLEASEBE CLEAR WITH EACH STEP AND YOUR HAND WRITTING AS WELL. IF POSSIBLE USE (TEXT) KEYBOARD TO ANSWER THE QUESTION IF NOT BE CLEAR WITH YOUR WRITING. BELOW IS THE FORMAT IN WHICH THE PROBLEM NEEDS TO BE SOLVE SO IS EASIER TO UNDERSTAND.

You stand on the top of a tall building and throw a baseball directly downwards. When the baseball leaves your hand, it has a speed of 6 m/s. (Assume there is no air resistance for this problem) a. Four seconds after you throw it, what is the acceleration of the baseball? Show your work and explain your steps. b. Four seconds after you throw it, what is the velocity of the baseball? Show your work and explain your steps.

PHET Step 12: Sketch this track and label where the 5 spots could be. a. He is at his maximum speed b. He is stopped c. He is going his average speed He is going slow e. He is going fast d.

Look at the slope of each graph, what does the difference between slopes tell you about velocity and speed in each experiment? (hint: the magnitude of the speed is not the same) Question 2: Compare graph (c) with graph (d). Look at the slope of each graph, what does the difference between slopes tell you about your velocity and speed in each experiment? (hint:speed and velocity are not the same thing) Question 3: Compare your graphs for (b) and (d). Which one has a positive slope and which one a negative one? What does this say about the direction you are moving? ty!

1. Using the position-time graph below, calculate the velocity (slope) for each time interval below.Show all your work including directions and units A) Velocity from pointA to B B) Velocity from B to C C) Velocity from C to D

The DETECTOR IS AT THE ORIGIN (position of 0). Choose the statements that accurately describe the motion of the car f GRAPH T At the end the cart is moving with constant speed. 10:At the end the cart is at rest. U Initially the cart moves away from the detector. As the cart is moving, its speed increases. position O Initially the cart moves toward the detector. As the cart is moving, its speed decreases.
