Horizontal speed of the ball is given as
height of the ball is given as
now the time taken by the ball to reach the bottom is given as
now we will plug in all values
now the distance from the base is given as
`
so it will land at distance of 40.4 m
Force
or motion im not toatally sure
Given Information:
Mass = m = 95 kg
Initial velocity = v₁ = 0 m/s
Final velocity = v₂ = 3 m/s
time = t = 15 seconds
Required Information:
magnitude of average force = ?
Answer:
magnitude of average force = 19 N
Explanation:
From the Newton's second law of motion
F = ma
From the kinematics equations,
v₂ = v₁ + at
at = v₂ - v₁
a = (v₂ - v₁)/t
a = (3 - 0)/15
a = 0.2 m/s²
F = 95*0.2
F = 19 N
Therefore, the magnitude of the average force required to bring the sled to rest is 19 N.
The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. The sun heats the earth's surface and the Earth heats the air above it, causing wind.
Chloroplast is only found in plant cells because they omit a green pigment which is highly
Important for photosynthesis. Hope it helps!
