Suppose you walk 18.0 m straight west and then 25.0 m straight north, how far are you from your starting point? answer

Physics

1 answer:

KatRina [158]4 years ago

4 0

Solution:

Since the directions are perpendicular,

So we must use Pythagoras theorem:

d = √(18.0² + 25.0²) m = 30.8 m

Thus,

This the required distance from the starting point.

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,

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

T = 17649.03 N = 17.65 KN
