a helicopter rises vertically, carring aload of concrete to make the foundation for a ski lift. a 35kg bagof concrete is resting on a scale in the helicopter. a constructoinworker in the copter notes that the scale reads 280N. what is thehelicopter's acceleration? a helicopter rises vertically, carring aload of concrete to make the foundation for a ski lift. a 35kg bagof concrete is resting on a scale in the helicopter. a constructoinworker in the copter notes that the scale reads 280N. what is thehelicopter's acceleration?
Explanation / Answer
mass m = 35 kg weight of the bag = mg = 35 *9.8 = 343 N Scale reading R = 280 N we know R = m( g - a ) 280= 343 - ma ma =343 -280= 63 a = 63/ m = 1.8 m / s ^ 2
