Answer:
The time taken for the paint ball to hit the ground is 
The distance of the landing point from the tower is 
Explanation:
From the question we are told that
The height of the tower is 
The speed of the paintball in the horizontal direction is 
Generally from kinematic equation we have that
Here u is the initial velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally
a is equivalent to 
t is the time taken for the paintball to hit the ground
So
=>
Generally the distance of its landing position from the tower is
=> 
=>
Answer:
2.4 m/s". 1
Explanation:
A jet with mass m = 8 x 10* kg jet accelerates down the runway for takeoff at 2.4 m/s". 1
Answer:
Explanation:
Here's the info we have:
initial velocity is 20 m/s;
final velocity is our unknown;
displacement is -10.2 m; and
acceleration due to gravity is -9.8 m/s/s. Using the one-dimensional equation
v² = v₀² + 2aΔx and filling in accordingly to solve for v:
Rounding to the correct number of sig fig's to simplify:
to get
v = 
If you don't round like that, the velocity could be 24, or it could also be 24.5 depending on how your class is paying attention to sig figs or if you are at all.
So either 20 m/s or 24 m/s
