Answer:
30 m/s
Explanation:
Applying,
v = u+at................ Equation 1
Where v = final speed of the ball, u = initial speed of the ball, a = acceleration, t = time.
From the question,
Given: u = 0 m/s (stationary), a = 600 m/s², t = 0.05 s
Substitute these values into equation 5
v = 0+(600×0.05)
v = 30 m/s
Hence the speed at which the ball leaves the player's boot is 30 m/s
Answer:
Un'auto si muove lungo un percorso rettilineo con velocità variabile come mostrato in figura. Quando l'auto è in possesso di A, la sua velocità è 10 ms-1 e quando è in posizione B, la sua velocità è 20 ms-1. Se l'auto impiega 5 secondi per spostarsi da A a B, trova l'accelerazione dell'auto.
Explanation:
F=ma Force is equal to mass times acceleration.
So looking at the equation if mass stays the same but we make F three times larger then acceleration will become 3 times larger as well because the equation must remain equal on both sides.
just multiply both sides of the equation F=ma times 3. So 3xF=3x ma
Answer:
A longitudinal wave is a type of mechanical wave, or wave that travels through matter, called the medium. In a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. Places where particles of the medium crowd closer together are called compression's.
Explanation:
I guess the problem is asking for the distance between Earth and Mars in Astronomical Units (AU).
Since
and the distance between the two planets is
we can convert this distance into AU by using the following proportion:
from which we find
