Question

A marble is projected from a card stock catapult at a point 18 cm above the floor. If the marble is given an initial velocity of 8 m/s at an angle of 50°, find:

A) 0.81 s
B) 1.03 s
C) 1.25 s
D) 1.46 s

Answer 1

The time of flight for the marble is approximately 1.03 seconds.

Step-by-step explanation:

To find the time of flight for the marble, we can use the equation:

time = 2 * (initial velocity * sin(angle)) / g

Where the initial velocity is 8 m/s and the angle is 50°. Plugging in these values, we get:

time = 2 * (8 * sin(50°)) / 9.8

Calculating this, we find that the time of flight is approximately 1.03 seconds.

Therefore, the correct answer is Option B) 1.03 s.
