A 578 Newton person takes an elevator from the first floor to the second floor of a building. The elevator quickly accelerates at a rate of 1.1 m/s^2 and then moves at a constant speed. Find the passenger's apparent weight during this period of acceleration.

Question

A 578 Newton person takes an elevator from the first floor to the second floor of a building. The elevator quickly accelerates at a rate of 1.1 m/s^2 and then moves at a constant speed. Find the passenger's apparent weight during this period of acceleration.

(578N)(9.8)=5664.4N is the true weight
5664.4N-(578n)(1.1)=1132.57N apparant weight.

Is this correct?

Answer 1

Yes, your solution is correct! To find the passenger's apparent weight during the period of acceleration, you correctly calculated the passenger's true weight as 578 N multiplied by the acceleration due to gravity, 9.8 m/s^2, which gives you 5664.4 N.

Then, to find the apparent weight, you subtracted the product of the passenger's mass (578 N) and the acceleration of the elevator (1.1 m/s^2) from the true weight. This gives you a value of 1132.57 N as the passenger's apparent weight during the period of acceleration.

Well done!
