The position of a ball as a function of time is given by

Physics
1 answer:
Andre45 [30]3 years ago
6 0

Answer:

x = -6.5 meters

Explanation:

The position of a ball as a function of time t is given by :

x=3\ m+(-5\ m/s)t..................(1)

Where t is time in seconds

We need to find the position of the ball at 1.9 s. It can be simply calculated putting t = 1.9 s in equation (1) as :

x=3+(-5)(1.9)

x = -6.5 meters

So, the position of the ball at 1.9 seconds is -6.5 meters. Hence, this is the required solution.

A football is kicked from ground level at an angle of 38 degrees. It reaches a maximum height of 9.7 meters before returning to
dem82 [27]

Answer:

Football will be in air for 2.8139 sec

Explanation:

We have given maximum height h = 9.7 meters

Angle of projection \Theta =38^{\circ}

We know that maximum height is given by h=\frac{u^2sin^2\Theta }{2g}

So 9.7=\frac{u^2sin^{2}38^{\circ} }{2\times 9.8}

u^2=501.5842

u = 22.396 m/sec

Time of flight is given by

T=\frac{2usin\Theta }{g}=\frac{2\times 22.396\times \times sin38^{\circ}}{9.8}=2.8139sec

The surface of the paper is phosphorescent. When light shines on it, some of the energy is absorbed and re-emitted slowly over t
Ad libitum [116K]

Answer:

No

Explanation:

Recall that the hierarchy of wavelength color from minimum wavelength to maximum wavelength is:

V < I < B < G < Y < O < R; and

E  \ \alpha  \ \dfrac{1}{\lambda}

As a result, blue light has a higher energy level than green and red light.

As a result, the surface glows due to the blue LED. The green LED, on the other hand, would not allow the surface to glow as much as the red LED, which has a lower energy level when compared to the green light. As a result, the red LED would not allow the surface to glow as well.
