Projectile Motion and Distance Calculations

The video tutorial explains how to calculate the total distance traveled by a stone thrown upwards from a building. The stone is thrown with an initial speed of 25 m/s and falls to the ground in 10 seconds. The problem is broken into two parts: the upward motion until the stone reaches its peak and the downward motion until it hits the ground. Using equations of motion, the distances for each part are calculated separately and then summed to find the total distance of 312.5 meters.

What is the initial speed of the stone thrown by Pratik?

• 25 m/s

• 20 m/s

• 30 m/s

• 15 m/s

How long does it take for the stone to fall to the ground?

• 15 seconds

• 10 seconds

• 5 seconds

• 20 seconds

What is the acceleration due to gravity used in this problem?

• 8 m/s²

• 9.8 m/s²

• 12 m/s²

• 10 m/s²

What is the final velocity of the stone at its highest point?

• 5 m/s

• 0 m/s

• 15 m/s

• 10 m/s

What equation is used to calculate the distance traveled during the upward motion?

• F = ma

• V² = U² + 2aS

• S = ut + 0.5at²

• V = U + at

What is the distance traveled by the stone during its upward journey?

• 31.25 meters

• 25.75 meters

• 35.50 meters

• 20.25 meters

How much time does the stone take to reach its highest point?

• 1.5 seconds

• 2.5 seconds

• 4.5 seconds

• 3.5 seconds

What is the distance traveled by the stone during its downward journey?

• 281.25 meters

• 300.50 meters

• 320.75 meters

• 250.25 meters

What is the total distance traveled by the stone?

• 312.5 meters

• 350 meters

• 325 meters

• 300 meters

Why is the negative sign ignored when calculating the total distance?

• Because it is a convention

• Because distance is a scalar quantity

• Because it is not important

• Because it simplifies the calculation
