Final answer:
To find the angle at which the stone leaves the catapult, we can use the concept of projectile motion. The angle at which the stone leaves the catapult is approximately 2.80 degrees.
Step-by-step explanation:
To find the angle at which the stone leaves the catapult, we can use the concept of projectile motion. The horizontal speed of the stone is 50 mph and the distance traveled is 100 ft. We can use the formula:
distance = horizontal speed × time
Since we are given the distance and the speed, we can rearrange the formula to solve for time:
time = distance / horizontal speed
Substituting the given values:
time = 100 ft / 50 mph
Converting the time to seconds:
time = (100 ft / 50 mph) × (1 hr / 3600 sec) × (5280 ft / 1 mile)
time = 1.47 seconds
Now we can use the equation for projectile motion:
distance = horizontal speed × time
Solving for the angle:
angle = arctan(distance / (horizontal speed × time))
Substituting the given values:
angle = arctan(100 ft / (50 mph × 1.47 sec))
angle = arctan(100 ft / (50 mph ÷ (1 hr / 3600 sec) × (5280 ft / 1 mile) × 1.47 sec))
angle = arctan(0.049)
angle = 2.80 degrees
