4kg(2.4+9.8)
4(12.2)
48.8N
A 4 kg object is suspended by a string from the ceiling of an elevator.
The acceleration of gravity is 9.8 m/s2 .
Determine the tension in the string if it is accelerating upward at a rate of 2.4 m/s2.
Answer in units of N
part 2

PART 2
m(g-a)
=4(9.8-2.4)
=4(7.4)
=29.6
m(g-a)
=4(9.8-2.4)
=4(7.4)
=29.6
