Agirl throws a marshmallow that lands in her friends mouth 92m away. the girl threw the marshmallow at an angle of 67 degrees. how hard was did she throw the marshmallow?

The girl threw the marshmallow with a speed  of 35.4 m/s.

Explanation:

Use the formula for the range of projectile motion:

with R the range or distance (92m), theta the elevation angle (67 degrees) and g the gravitational acceleration. The velocity can be determined from this as follows:

The girl threw the marshmallow with a speed  of 35.4 m/s, which is approximately 79 mph. No word on the boy's condition after the marshmallow's landing.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
