Answer:

32 m/s²

Explanation:

Centripetal acceleration is:

a = v² / r

Given v = 8 m/s and r = 2 m:

a = (8 m/s)² / (2 m)

a = 32 m/s²

Answer:

$\theta=23.7^{\circ}$

Explanation:

The ratio of pressure 2 to 1 us 5.48/1= 5.48 rounded off as 5.5.

Referring to table A.2 of modern compressible flow then $M_{\beta_1}=2.2$

Also

$M_{\beta_1}=M_1 sin \beta$ and making $sin\beta$ the subject of the formula then

$sin\beta=\frac {2.2}{3.5}\\\beta=38.94^{\circ}$

Making reference to $\theta-\beta-M$ diagram then

$\theta=23.7^{\circ}$

A player cathces a ball. Consider the action force to be the impact of the ball against the players glove. What is the reaction

Anuta_ua [19.1K]

Force the glove exerts on the ball

Explanation:

The reaction to this force is the force the glove exerts on the ball.

According to Newton's third ;aw of motion "Action and reaction forces are equal and opposite in direction".

The action force is the impact of the ball against the players glove.
The reactive force is the force the glove exerts on the ball.

This reactive force is directed in the opposite direction and it is the reason why the motion of the incoming ball is halted.

An object of 4 kg has a speed of 6 m/s and moves a distance of 8 m. What is its kinetic energy in joules.

11Alexandr11 [23.1K]

Answer:

The answer to your question is Ke = 72 J

Explanation:

Kinetic energy depends on the speed of and object and its mass.

Data

mass = m = 4 kg

speed = v = 6 m/s

distance = d = 8 m

Kinetic energy = ke = ?

Formula

Ke = (1/2) mv²

Substitution

Ke = (1/2) (4)(6)²

Simplification

Ke = (1/2)(4)(36)

Ke = (1/2)(144)

Ke = 72 Joules

Result

Ke = 72 J
