Rectilinear motion example problem

The video tutorial presents a challenging rectilinear motion problem involving a car and a biker. The car travels at a constant speed of 120 km/h, while the biker starts 2 seconds later, accelerates, and reaches a maximum speed of 150 km/h. The problem is analyzed using time-position and velocity-time graphs, and solved using mathematical formulas for acceleration and velocity. The solution involves calculating the distance the biker must travel to meet the car, considering different scenarios. The tutorial concludes with insights on the problem-solving process.

What is the initial speed of the car in the problem?

• 120 km/h

• 180 km/h

• 150 km/h

• 100 km/h

How long does it take for the biker to start chasing the car?

• 3 seconds

• 2 seconds

• 4 seconds

• 1 second

What is the maximum speed the biker can reach?

• 150 km/h

• 140 km/h

• 130 km/h

• 120 km/h

In the velocity-time graph, what does the area under the curve represent?

• Time elapsed

• Acceleration

• Distance traveled

• Velocity

What is the acceleration of the biker?

• 7 m/s²

• 6 m/s²

• 5 m/s²

• 4 m/s²

What is the significance of the intersection point in the velocity-time graph?

• It shows when the biker stops

• It indicates when the biker meets the car

• It marks the start of the biker's journey

• It represents the biker's maximum speed

What is the formula used to calculate the area under the velocity-time curve?

• V = DX/DT

• A = DV/DT

• Area = V * T

• Area = 1/2 * base * height

What is the calculated time at which the biker meets the car?

• 27.34 seconds

• 28.34 seconds

• 26.34 seconds

• 25.34 seconds

What is the distance the biker travels to meet the car?

• 912 meters

• 910 meters

• 900 meters

• 920 meters

If T2 was less than T1, what would it imply?

• The biker meets the car before starting

• The biker meets the car after reaching max speed

• The biker never meets the car

• The biker meets the car while accelerating
