A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance. The student hits the elevator button and it begins to move upwards. While the elevator is moving, the student records this information Time = 0 to 3.0 sec the balance reads 278 grams Time = 3.0 - 12 sec the balance reads 240. grams Time = 12.0 to 15.0 sec the balance reads 192 gram How far up (in meters) did the elevator travel? Consider: UP to be (+), DOWN to be (-) and g =9.8 m/s2 . ROUND YOUR ANSWER TO A WHOLE NUMBER of meters (no decimal places) HINT: This problem requires finding THREE different displacements and adding them up! 2nd HINT: You will need to (A) use your equations of motion or (B) make a v-t graph to find those displacements!
