A boy in a tower throws a ball a distance of 60 meters. If the ball is launched from 20 m above the ground, at what speed is the
ball thrown?
1 answer:
The speed the ball was projected upwards is 29.7 m/s.
The given parameters;
- height in which the ball was thrown, h = 20 m
- distance traveled by the ball, X = 60 m
The time of motion of the ball to travel to the given height is calculated as;
The horizontal speed in which the ball was projected upwards is calculate as;
X = (v₀ₓ)t
60 = 2.02v₀ₓ
Thus, the speed the ball was projected upwards is 29.7 m/s.

Answer:
104.3 cm or 179.7
Explanation:
First find time that it takes for the object to hit the ground
*
Then find xf of projectile
not 100% sure if the projectile is going away from the object or towards it but you either do 142- 37.7 or 142+37.7
hope that helps
If it's a small object near another gigantic object, then we usually call that the small object's "weight".
