Question

Ann and Bob are carrying an 18.5 kg table that is 2.25 m long. An 8.33 kg box sits on the table 0.750 from Ann. How much lift force does Ann exert? Use 9.80 for gravity.

URGENT

Answer 1

The lift force that Ann exerts can be calculated using the formula:

F = (m1 + m2) * g * d2 / d1

Where F is the lift force, m1 is the mass of the table, m2 is the mass of the box, g is the acceleration due to gravity (9.80 m/s^2), d1 is the total length of the table, and d2 is the distance from Ann to the box.

Plugging in the given values, we get:

F = (18.5 kg + 8.33 kg) * 9.80 m/s^2 * 0.750 m / 2.25 m

F = 40.3125 N

Therefore, Ann exerts a lift force of 40.3125 N.
