graph is faster than using formulas. The area under a velocity-time graph gives the displacement.
Always establish a positive direction (usually right or up) and stay consistent. A negative velocity means the object is moving backward; negative acceleration means it is slowing down (if velocity is positive) or speeding up in the negative direction. rectilinear motion problems and solutions mathalino upd
A car traveling at 30 m/s applies its brakes and comes to a complete stop over a distance of 100 meters. Calculate the constant deceleration of the car and the time it took to stop. Solution: Identify knowns: Find Acceleration ( ): Use the formula: Find Time ( ): Use the formula: Problem 2: Variable Acceleration (Calculus-Based) graph is faster than using formulas
