Based on the data given, in what direction will the car accelerate?

skad [1K]

Vertical forces:
There is a force of 579N acting upward, and a force of 579N
acting downward.
The vertical forces are balanced ... they add up to zero ...
so there's no vertical acceleration.
Not up, not down.

Horizontal forces:
There is a force of 487N acting to the left, and a force of 632N
acting to the right.
The net horizontal force is

(487-left + 632-right) - (632-right - 487-right) = 145N to the right.

The net force on the car is all to the right.
The car accelerates to the right.

A cable is lifting a construction worker and a crate, as the drawing shows. The weights of the worker and crate are 965 N and 15

Alex777 [14]

Answer:(a)2631.46 N

(b)1605.51 N

Explanation:

Assuming there is a cable between crate and worker

Given

weight of worker $W_w=965 N$

Weight of crate $W_c=1510 N$

mass of worker $m_w=\frac{965}{g}=98.46 kg$

mass of crate $m_c=\frac{1510}{g}=154.08 kg$

acceleration of system $a=0.620 m/s^2$

Tension in the wire carrying Worker

$T-(m_w+m_c)g=(m_w+m_c)a$

$T=(m_w+m_c)(g+a)$

$T=(252.54)(9.8+0.62)$

$T=2631.46 N$

(b)Tension in the string above

$T_2-m_c\cdot=m_ca$

$T_2=m_c(g+a)$

$T_2=154.08(9.8+0.62)$

$T_2=1605.51 N$

You are playing right field for the baseball team. Your team is up by one run in the botton of the last inning of the game when

VARVARA [1.3K]

Answer:

The correct response is "No". The further explanation is given below.

Explanation:

The given values are:

Angle

$\theta = 30^{\circ}$

Distance

d = 20 m

Speed

s = 8.0 m/s

Now,

⇒ $y(t) = \frac{1}{2}\times a\times t^2 + v0\times t\times (sin \theta)$

$0 = -4.9t^2 + v0\times t\times (sin 30)$

$x = v0\times (cos \theta)\times t$

$65 = v0\times (cos 30)\times t$

$v0\times t = \frac{65}{Cos30}$

$0 = -4.9t^2 + 65\times \frac{sin30}{cos30}$

$t = 2.767 \ sec$

So,

⇒ $d = r\times t$

$20 = 8\times t$

$t=2.5 \ sec$

Therefore, 2.5 < 2.767, so it won't get there.
