A person throws a pumpkin at a horizontal speed of 4.0 — off a cliff. The pumpkin travels 9.5 m horizontally

Complete Question

A person throws a pumpkin at a horizontal speed of 4.0 m/s off a cliff. The pumpkin travels 9.5m horizontally before it hits the ground. We can ignore air resistance.What is the pumpkin's vertical displacement during the throw? What is the pumpkin's vertical velocity when it hits the ground?

Answer:

The pumpkin's vertical displacement is $H = 27 .67 \ m$

The pumpkin's vertical velocity when it hits the ground is $v_v__{f}} = 23.298 \ m/s$

Explanation:

From the question we are told that

The horizontal speed is $v_h = 4 m/s$

The horizontal distance traveled is $d = 9.5 \ m$

The horizontal distance traveled is mathematically represented as

$S = v_h * t$

Where t is the time taken

substituting values

$9.5 = 4 * t$

=> $t = \frac{9.5}{4}$

$t = 2.38 \ sec$

Now the vertical displacement is mathematically represented as

$H = v_v t + \frac{1}{2} a_v t^2$

now the vertical velocity before the throw is zero

So

$H = 0 + \frac{1}{2} (9.8) * (2.375)^2$

$H = 27 .67 \ m$

Now the final vertical velocity is mathematically represented as

$v_v__{f}} = v_v + at$

substituting values

$v_v__{f}} = 0 + (9.8)* (2.375)$

$v_v__{f}} = 23.298 \ m/s$

Briefly describe the difference between the behaviorist, nativist, and interactionist language acquisition theories.

Over [174]

Answer:

Described below

Explanation:

- The behaviorist theories: This theory is of the claim that language is learned through the means of reinforcement and imitation. This means that little children can mimic the language of individuals around them and also receive reinforcement to correct the formation of their words. Thereafter, words not reinforced will eventually no longer be in use.

- The nativist theories: This theory is of the claim that individuals possess an innate process which is used in language learning and is widely known as "language acquisition device" (LAD). This device is used to assist in helping them automatically learn languages.

-The interactionist theories: This theory is of the claim that innate processes which is also referred to as genetic predispositions and learning experiences from the environment both help in language development.
