Explanation:

Draw a free body diagram of the toolbox. There are two forces:

Weight force mg pulling down,

and applied force F pulling up.

Sum of forces in the y direction:

∑F = ma

F − mg = ma

45 N − 15 N = (3 kg) a

a = 10 m/s²

The answer should be B. It's possible the answer key has a mistake.

What is the force of repulsion between two points positive charges 5 and 8 separated at a distance of 0.02m apart

Zinaida [17]

Explanation:

F =(frac{1}{4{pi}{varepsilon}_o}) x (frac {q_1q_2}{r^2})

F =(frac {5 {times} 10 {times} 8 {times} 10}{0.002 {times} 0.002}) x 9 x 10

F = 900N

Two people pull on a horizontal spring that is attached to an immovable wall. Then, they detach it from the wall and pull on opp

zimovet [89]

Answer:In first case

Explanation:

When two People pull the spring, let the applied force by each person be $F_o$

and spring constant of spring be k

so Total force is $2F_o$

total extension according to Hooke's law is

$x=\frac{2F_o}{k}$

When they detach the spring and apply force in opposite direction then force on either side is F so net extension is

$x'=\frac{F_o}{k}$

so in first case there will be more extension

You are designing an elevator for a hospital. The force exerted on a passenger by the floor of the elevator is not to exceed 1.5

inn [45]

Answer:

maximum speed of the elevator is 6.54 m/s

Explanation:

given,

force exerted on the elevator is 1.59 times passenger weight.

when the elevator accelerates upward with rate of a.

total force

F = m × (a+g)

1.59× mg = ma + mg

0.59 mg = ma

a = 0.59 g

we also have that

$v^2 = u^2+ 2 a s$

$v =\sqrt{2a*s}$

= $\sqrt(2\times 0.59\times 9.8\times 3.7)$

= 6.54 m/s

maximum speed of the elevator is 6.54 m/s
