A scene in a movie has a stuntman falling through a floor onto a bed in the room below. The plan is to have the actor fall on his back, but a researcher has been hired to investigate the safety of this stunt. When the researcher examines the mattress, she sees that it effectively has a spring constant of 77144 N/m for the area likely to be impacted by the stuntman, but it cannot depress more than 14.87 cm without injuring him. To approach this problem, consider a simplified version of the situation. A mass falls through a height of 3.72 m before landing on a spring of force constant 77144 N/m. Calculate the maximum mass that can fall on the mattress without exceeding the maximum compression distance. maximum mass: kg Based on this crude measurement, is the stunt safe using the proposed mattress? yes no cannot determine

Transcribed Image Text:A scene in a movie has a stuntman falling through a floor onto a bed in the room below. The plan is to have the actor fall on his
back, but a researcher has been hired to investigate the safety of this stunt. When the researcher examines the mattress, she sees
that it effectively has a spring constant of 77144 N/m for the area likely to be impacted by the stuntman, but it cannot depress
more than 14.87 cm without injuring him.
To approach this problem, consider a simplified version of the situation. A mass falls through a height of 3.72 m before landing
on a spring of force constant 77144 N/m. Calculate the maximum mass that can fall on the mattress without exceeding the
maximum compression distance.
