4. The plot below shows the velocity of a hockey puck as a function of time. The puck
starts at time t=0 at position x-3 m in the positive direction. All quantities are measured
in SI units (meters and seconds).
v (m/s)

t(s)
a) Draw sketches of corresponding position
versus time and acceleration versus time for
the puck. The time axis is identical for all 3
graphs/sketches (this one, position,
acceleration graphs)
At time t-4s, what is the puck's position?
At time t-3s, what is the puck's
acceleration?

Introduction:
We are given velocity versus time graph. We draw position vs time and acceleration vs time graph by studying the above graph. The velocity in the graph is either increasing or decreasing linearly or is constant. We then can find the position and accelerations in given time. We know that when velocity is constant there is no acceleration acting.

The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. vb vb Downstream positive Vr Upstream negative Vrarrow_forwardPls help ASAParrow_forward
