*Look at attachment for photo of object**
prohojiy [21]

A. The magnitude of the spring force (in N) acting upon the object is 15.9 N

B. The magnitude of the object's acceleration (in m/s²) is 30.58 m/s²

C. The direction of the acceleration vector points toward the equilibrium position (i.e., to the left in the figure).

<h3>A. How to determine the force </h3>
  • Extension (e) = 0.150 m
  • Spring constant (K) = 106 N/m
  • Force (F) = ?

F = Ke

F = 106 × 0.15

F = 15.9 N

<h3>B. How to determine the acceleration</h3>
  • Mass (m) = 0.52 Kg
  • Force (F) = 15. 9 N
  • Acceleration (a) =?

F = ma

Divide both sides by m

a = F / m

a = 15.9 / 0.52

a = 30.58 m/s²

<h3>C. How to determine the direction of the acceleration vector</h3>

Considering the diagram, we can see that the spring was pulled away from the equilibrium point.

Thus, when the spring is released, it will move toward the equilibrium point. This is also true about the acceleration.

Therefore, we can conclude that the direction of the acceleration vector is towards the equilibrium point.

A body is projected vertically upwards with a velocity of 10m/s from a vertically upward position at height h another body is dr
RoseWind [281]

Answer:

0.25 second  

Explanation:

Given :

Velocity, v = 10 m/s

The height,

$ h = \frac{v^2}{2g} $

$ h = \frac{10^2}{2\times 9.8} $

   = 5 m

Therefore the time at which both the bodies meet is

$ t = \frac{h}{v+v} $

$ t = \frac{5}{10+10} $

$ t = \frac{5}{20}  = 0.25$

So, time taken is 0.25 seconds

A grating has 380 lines/mm. How many orders of the visible wavelength 457 nm can it produce in addition to the m = 0 order? Plea
egoroff_w [7]

Answer:

5 orders.

Explanation:

The  condition for diffraction maxima,

sin \theta = mN\lambda\\m=\frac{sin \theta}{N\lambda}

m=\frac{sin 90^{\circ}}{(380\frac{lines}{mm}(\frac{1000mm}{1m} )) 457\times 10^{-9} m }\\m=5.75\simeq5

So maximum m is 5 which means it produce 5 orders.

Therefore, the number of possible order will produce by visible light of wavelength 457 nm is 5 orders.

A 1400 kg car moving +13.7 m/s makes an elastic collision with a 3200 kg truck, initially at rest. What is the velocity of the c
marishachu [46]

Answer:

-13.7m/s

Explanation:

If the car has a mass of 1400kg with a speed of +13.7m/s -> hits [email protected] rest and bounces with an elastic collision:

fm = -fm

Therefore, the speed the car will possess will be at a negative state.

= -13.7m/s
