1. The problem statement, all variables and given/known data A male and female pair of dancers start dancing when the male lifts the female and throws her into the air. The female's mass is 40kg . The male exerts an average vertical force of 500n for 1.0s on the female. What is her vertical velocity when she is released into the air ? 2. Relevant equations I chose to go with Force x Change in time = Mass x Change in Velocity FΔt = mΔv 3. The attempt at a solution So I initially came up with 500N x 1.0s = 40kg x Change in velocity (500N x 1.0s)/ 40kg = Change in Velocity Change in velocity = 12.5 The correct answer (if 9.81 m/s is used for g) is 2.69 m/s upwards. I hadn't accounted for g in my answer and am not sure how to incorporate it.
