Pegs A and B are restricted to move in the elliptical slots due to the motion of the slotted link. (Figure 1) Figure 1 of 1 X v-10 m/s ▼ Part A If the link moves with a constant speed of 10 m/s, determine the magnitude of the velocity of peg A when x = 0.7 m. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) V = Submit Part B. Value μA Submit HA a= Value Units Determine the magnitude of the acceleration of peg A when x = 0.7 m. Express your answer to three significant figures and include the appropriate units.

Activity 1.16- Projectile Motion Problems Note: Neglect air friction unless otherwise specified. Use g = +10 m/s² for the magnitude of the acceleration due to gravity. 1. You throw a snowball from a roof with a speed of 20 m/s at an angle of 36.87" above the horizontal. The ball lands at a horizontal distance of 48 meters from where you throw the snowball. Assume free fall. a. Use the diagram below and problem statement above to complete the table. Write in values if given in the problem statement (or easily calculated). Use a question mark if the value is not given in the problem statement. Use the origin and +x and ty directions shown. Ya 16-20 (0,0) ! +y 9 = 36.87 48 m Vaz- x= V₂ = b. How long is the ball in the air? Start by writing the relation you use symbolically. C How high is the roof? Start by writing the relation you use symbolically By y= Vy= d. What is the speed and direction of the snowball just before it hits the ground? Give angle relative to vertical with zero degrees…

The figure shows two dots of a motion diagram and vector 7₁. Draw the next velocity vector 2 if the acceleration vector a at dot 2 points up. Draw the vector starting at the black dot 2. The location and orientation of the vector will be graded. The exact length of your vector will not be graded but the length relative to vector v₁ will be graded. + Σ B No elements selected I Select the elements from the list and add them to the canvas setting the appropriate attributes. i ?

Keeping your sign conventions for direction is very important.all velocity directed down must be negative, and all velocity directed up must be positive. 2. A college student drops his textbook out a second story window in the Oswald Building, which is 12m above the ground. a) What is the velocity of the book just before it hits the ground? b) 5m/s, what would the velocity of the book be just before it hit the ground? If the student had instead thrown the book upward with an initial velocity of
