Answer:
The net force acting on the person is, F = 560 N
Explanation:
Given data,
The downward acceleration of the elevator, a = 1.8 m/s²
The weight of the person is, W = mg
= 686 N
Therefore the mass of the person,
m = W /g
= 686 / 9.8
= 70 kg
The net force acting on the person,
F = mg - ma
= 686 - 70 x 1.8
= 560 N
Hence, the net force acting on the person is, F = 560 N
Answer:
Explanation:
r = √(-6.48² + 12.58²) = 14.1508586311... 14.15
θ = arctan(12.58 / -6.48) = 117.25314692... 117.25
(r, θ) = (14.15, 117.25)
