A car's motion is described by a velocity-time graph. The car starts from rest and accelerates uniformly to a velocity of 10 m/s in 5 s. It then travels at this constant velocity for another 5 s. Finally, it decelerates uniformly to a stop in 5 s. What is the car's total displacement during the entire 15 s journey?
A bus, initially at rest, accelerates to a velocity of 15 m/s in 3 s. It then continues to accelerate at the same constant rate for an additional 7 s. What is the total distance the bus has traveled?
A tiny charged particle of mass 2×10⁻³ kg is placed in a uniform electric field and starts from rest. The field exerts a constant force of 4 N on it. Calculate the distance travelled in 10 s.
A toy car moves along a circular track of radius 5 m. It travels at 20 m/s for 5 s, then slows down uniformly to rest in 5 s. Calculate the total distance travelled along the track.
Velocity is defined as:
A body moves with constant velocity. Its acceleration is:
