Answer:
30m/ s
Explanation:
this is an example of a projectile, where the path traced by the ball will be a downward parabola.
one must know that the <em>vertical velocity of an object having projectile motion is zero at the top of its trajectory</em> and that the <em>horizontal velocity remains constant throughout</em>.
this means, at the top of the trajectory the <u>ball's overall speed will be equal to its horizontal velocity</u>.
and horizontal velocity is given 30 m/s
hence, overall speed of the ball = 30m/ s
Answer:
1.4 m/s
Explanation:
The minimum speed will be when the diver's initial velocity is horizontal.
First, find the time it takes for the diver to fall 10 meters.
Given:
Δy = 10 m
v₀ᵧ = 0 m/s
aᵧ = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
10 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 1.43 s
Now find the initial horizontal velocity.
v = (2 m) / (1.43 s)
v = 1.4 m/s
Answer:
Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz).
Explanation:
An electric current produces a magnetic field when the current flows through a wire. The correct answer will be A.
Your answer would be 94. This is because only 10 transfers, so 90 is lost from the mouse. It takes 4 for the cat to pounce. When you add 90 and 4 you get your answer.....94
