What quantity is the rate of change of velocity? Displacement Acceleration Final velocity

Physics
1 answer:
MariettaO [177]3 years ago
7 0

Answer:

Acceleration

Explanation:

The quantity of the rate of change of velocity is termed the acceleration of the body.

Acceleration is the rate of change of velocity with time;

  A  = \frac{v - u}{t}  

A is the acceleration

v is the final velocity

u is the initial velocity

t is the time taken

true or false:acceleration toward the center of a curved or circular path is called gravitational acceleration.
nalin [4]
Nope. It's called 'centripetal' acceleration. The force that created it MAY be gravitational, but it doesn't have to be. For things on the surface of the Earth moving in circles, it's never gravity.

A block of mass 1.5 hangs at the of end of a weight cord suspended from the ceiling.what is the tension in the cord, and with wh
Len [333]

The tension in the cord is 14.7 N and the force of pull of the cord is 14.7 N, assuming the block is stationary.

<h3>What is the tension in the cord?</h3>

The tension in the cord is calculated as follows;

T = ma + mg

where;

  • a is the acceleration of the block
  • g is acceleration due to gravity
  • m is mass of the block

T = m(a + g)

T = 1.5(a + 9.8)

T = 1.5a + 14.7

Thus, the tension in the cord is (1.5a + 14.7) N.

If the block is at rest, the tension is 14.7 N.

<h3>Force of the force</h3>

The force with which the cord pulls is equal to the tension in the cord

F = T = m(a + g)

F = (1.5a + 14.7) N

If the block is stationary, a = 0, the tension and force of pull of the cord = 14.7 N.

Thus, the tension in the cord is 14.7 N and the force of pull of the cord is 14.7 N, assuming the block is stationary.

Red fox
Svetach [21]
In a food pyramid, the organism that has the least amount of total energy available is the one that is in the bottom or last. In this case, given the list of organisms above, the organism that would have the least amount of total energy available would be the RED FOX. The answer is option A. Hope this answer helps.

AlekseyPX

Answer:

t = 0.93 s

Part b)

d = 3.98 m

Part c)

v_x = 4.28 m/s

v_y = -11.49 m/s

Explanation:

The two components of the velocity of the ball is given as

v_x = 4.9 cos29

v_x = 4.28 m/s

v_y = 4.9 sin29

v_y = 2.37 m/s

Part a)

now we know that the displacement in y direction is given as

\Delta y = 6.4 m

so we have

\Delta y = v_y t + \frac{1}{2}gt^2

6.4 = 2.37 t + 4.9 t^2

t = 0.93 s

Part b)

Distance of the ball in x direction of the motion is given as

d = v_x t

d = 4.28 \times 0.93

d = 3.98 m

Part c)

In x direction the velocity will remain the same always

v_x = 4.28 m/s

while in Y direction we can use kinematics

v_y = v_{oy} + at

v_y = -2.37 - 9.81(0.93)

v_y = -11.49 m/s
