Answer:

100 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 5 kg

Acceleration (a) = 20 m/s

Force (F) =?

Force is simply defined as the product of mass and acceleration. Mathematically, it can be expressed as:

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can obtain the force need to move the object. This can be obtained as follow:

Mass (m) = 5 kg

Acceleration (a) = 20 m/s

Force (F) =?

F = ma

F = 5 × 20

F = 100 N

Therefore, a force of 100 N is needed to move the object.

An elevator filled with passengers has a mass of 1603 kg. (a) The elevator accelerates upward from rest at a rate of 1.20 m/s2 f

Galina-37 [17]

Answer:

T = 17649.03 N = 17.65 KN

Explanation:

The tension in the cable must be equal to the apparent weight of the passenger. For upward acceleration:

$T = W_A = m(g+a)\\$

where,

T = Tension in cable = ?

$W_A$ = Apparent weight

m = mass = 1603 kg

g = acceleration due to gravity = 9.81 m/s²

a = acceleration of elevator = 1.2 m/s²

Therefore,

$T = (1603\ kg)(9.81\ m/s^2+1.2\ m/s^2)\\\\$
