Question

A 4.0 kg toy car can move along an x axis. The figure gives Fx of the force acting on the car, which begins at rest at time t = 0. The scale on the Fx axis is set by Fxs = 4.0 N. In unit-vector notation, what is  P→ at (a)t = 6.0 s and (b)t = 2.0 s,(c) what is  v→ at t = 5.0 s?

The image depicts a graph illustrating the force \( F_x \) (in newtons) as a function of time \( t \) (in seconds). The horizontal axis represents time, labeled \( t \) (s), ranging from 0 to 10 seconds, while the vertical axis represents force, labeled \( F_x (N) \). Key features of the graph: 1. The force \( F_x \) starts at a positive maximum value, \( F_{xs} \), at time \( t = 0 \). 2. The graph remains constant at \( F_{xs} \) until \( t = 2 \) seconds. 3. From \( t = 2 \) to \( t = 5 \) seconds, the force decreases linearly from \( F_{xs} \) to \(-F_{xs}\). 4. At \( t = 5 \) seconds, the force reaches \(-F_{xs}\) and remains constant until \( t = 8 \) seconds. 5. Finally, from \( t = 8 \) to \( t = 9 \) seconds, the force rapidly increases back to zero. 6. From \( t = 9 \) to \( t = 10 \) seconds, the force stays constant at zero. The graph is a visual representation of how the force \( F_x \) changes over time, illustrating both constant and linearly changing segments.
