A player hits a tennis ball in the air with an initial velocity of 32 meters per second at 35 degrees from the vertical how fast
Mamont248 [21]

Answer: 18.35 m/s

Explanation:

At the highest point of trajectory, the vertical component of the velocity would be zero and the tennis ball would have horizontal component of velocity.

It is given that the initial velocity of the ball is 32 m/s and it makes 35° with the vertical. Hence the horizontal component of the velocity,

v sin θ = 32 m/s × sin 35° = 18.35 m/s

Hence, at the highest point in its trajectory, the tennis ball would be moving with the speed  18.35 m/s.

Vikentia [17]

Answer:

Ray A = Incidence ray

Ray B = Reflected ray

Explanation:

From the law of reflection,

Normal: This is the line that makes an angle of 90° with the reflecting surface.

Ray A is the incidence ray: This is the ray that srikes the surface of a reflecting surface. The angle formed between the normal and the incidence ray is called the incidence angle

Ray B is the reflected ray: This is the ray leaves the surface of a reflecting surface. The angle formed between the reflected ray and the normal is called reflected angle

Calculate their speed between points A and B. Include the units.
N76 [4]
<h3>Speed between point A and B</h3>

= Total Distance/Total time

= 30/3

= 10 km/h

<h3>Average speed for this ride</h3>

Average speed = Total distance travelled/time taken

= 50/6

= 8.3 km/h
