These are the kinematic equations for motion that represent the position, velocity, and acceleration of an object as functions of time : Set #1 Set #2 x = xo+ vot * x = xo+ vot+= at2 V = VO v = Vo+ at a = 0 a = constant where, x = position t = time v = instantaneous velocity a = a constant acceleration along the x axis xo = initial position at t = 0. Tells you where the object was at the moment you started counting time. Vo = initial velocity at t = 0.situation. b. Sketch the position-, velocity-, and acceleration-vs-time for both they x- and y-directions for this I - Position (m) time (s ) x- Velocity (m/'S) time (s ) x-Acceleration (mis!) me (5) y - Position ( m ) time (s) y - Velocity ( m/s ) time (s) Y - Acceleration (m/s') time (s ) c. Now the ball starts from rest but is tapped repeatedly in both the x and y directions, such that the bal starts to accelerate in the x and y directions equally. The ball follows the same path as before. Is this now projectile motion? Explain your reasoning. d. Sketch the position-, velocity-, and acceleration-vs-time for both the x- and y-directions for this new situation. Use the graphs in step b but use a different color or style. Question 24: A pitcher throws a ball in such a way that it leaves their hand directly horizontal. After the ball leaves thei hand is this motion considered projectile motion? Explain.Part A A hockey puck with mass 0.160 kg is at rest at the origin (x=0) on the horizontal, frictionless surface of the rink. At time t = 0 a player applies a force of 0.250 N to the puck, parallel to the x-axis; he What is the position of the puck at t = 2.00 s? continues to apply this force until t = 2.00 s. Express your answer in meters.

Use constant acceleration equations to calculate the effect of the acceleration on the motion. EXECUTE: During this time interval the acceleration is constant and equal to FI 0.250 N ar m 1.562 m/s2 0.160 kg We can use the constant acceleration kinematic equations from Chapter 2. x - To = Vort + 2axt2 = 0+ , (1.562 m/s2) (2.00 s)2 - 3.12 m, so the puck is at x = 3.12 m. x = Vor + art = 0 + (1.562 m/s2) (2.00 s) = 3.12 m/s Part B In this case what is the speed of the puck? Express your answer in meters per second. v = 3.12 m/sPart C A hockey puck with mass 0.160 kg is at rest at the origin (x=0) on the horizontal, frictionless surface of the rink. At time t = 0 a player If the same force is again applied at t = 5.00 s, what is the position of the puck at t = 7.00 s? applies a force of 0.250 N to the puck, parallel to the x-axis, he continues to apply this force until t = 2.00 s.
