Correct Question:

Compare the kinematics equation governing the motion y = v_{o} t + 1/2 g t^{2} and the format of the fit equation that you just made y = At^{2} + Bt + C to explain how you can use the coefficients (either A, B, or C) to calculate the acceleration due to gravity. 13 pts Identify the coefficients of your fit equation. 5 pts

A =

В =

C =

Answer:

A = g/2

B =  v₀

C = 0

g = 2A

Explanation:

y = v_{o} t + 1/2 g t^{2} .............................(1)

y = At^{2} + Bt + C............................(2)

Comparing equations (1) and (2)

A = g/2

B = v₀

C = 0

Acceleration due to gravity can be gotten from A = g/2 above

g = 2 A.....................(3)

Therefore, if we know the coefficient A, we can get the acceleration due to gravity using the relation in equation (3)

In a physics experiment, two equal-mass carts roll towards each other on a level, low-friction track. One cart rolls rightward a
xz_007 [3.2K]

Answer:

The correct answer is option a.

Explanation:

Conservation of momentum :

m_1u_1+m_2u_2=m_1v_1+m_1v_2

Where :

m_1, m_2 = masses of object collided

u_1,u_2 = initial velocity before collision

v_1,v_2 = final velocity after collision

We have :

Two equal-mass carts roll towards each other.

m_1=m_2=M

Initial velocity of m_1=u_1=2 m/s

Initial velocity of m_2=u_2=-1 m/s (opposite direction)

Final velocity of m_1=v_1=v (same direction )

Final velocity of m_2=v_2=v  (same direction)

M\times 2 m/s+M(-1 m/s)=Mv+Mv

1 m/s=2v

v = 0.5 m/s

rg135

The speed of the carts after their collision is 0.5 m/s.

A 82-kg skydiver has a speed of 40 m/s at an altitude of 490 m above the ground. Calculate the total mechanical energy of the sk
Sav [38]

Answer:

ME=459,364J

Explanation:

Mechanical Energy=Potential Energy+ kinetic Energy

m=82kg,g=9.8N/kg,h=490m,v=40m/s

To calculate Kinetic Energy:-

KE=\frac{1}[2}mv^2\\=\frac{1}{2}\times82kg \times(40m/s)^2\\=65600J

To calculate Potential Energy:-

PE=mgh\\=82kg \times9.8N/kg \times490\\=393764

therefore,

ME=KE+PE\\=65600+393764\\=459364J

The skydiver's total mechanical energy is 459365J

You lift a bowling ball with your hand, accelerating it upward. What are the forces on the ball and on what objects are they exe
Snowcat [4.5K]

Answer:

Explanation:

When we lift a ball with the hand the forces experienced by the ball is  

  • Force of your hand
  • Gravitational force

Resultant of these forces gives acceleration to the ball

While your hand exerts a force on the ball, the ball will also exert a force of equal magnitude but opposite in direction to the force by hand.

All these forces is exerted on the ball, hand or on the earth.

A 49.5 gram super ball traveling at 25.5 m/s bounces off a brick wall and rebounds at 19.5 m/s. a high-speed camera records this
OLga [1]
T = 4.25 ms = 4 x 10⁻³ s, the time for rebound
v₁ = 25.5 m/s, the impacting velocty
v₂ = -19.5 m/s, the rebounding velocity (n the opposite directon)

The change in velocity is
v₂ - v₁ = - (25.5+19.5) = -45 m/s

The acceleration is
a = (-45 m/s)/(4 s) = -11.25 m/s²
The negative sign indicates that the final velocity is opposiye to the impact velocty.

Answer: The magnitude of the acceleration is 11.25 m/s²
