Answer:
Explanation:
(a)
From the given information:
The initial velocity 
= 5 m/s
The direction of the angle θ = 30°
Therefore, the component along the x-axis = 
The component along the y-axis = 
To find the final velocity( reflected velocity)
using the same magnitude 
The angle from the x-axis can be 
= 150°
Thus, the component along the x-axis = 
The component along the y-axis = 
(b)
The velocity can be written as in vector form.
---- (1)
The reflected velocity in vector form can be computed as:
--- (2)
The change in velocity = 
(c)
The magnitude of change in velocity = 
= 8.66 m/s
Answer:
It doesn’t really relate
Explanation:
heavier load the parachute must be moving faster to match the downward force of the greater load
and approx terminal velocity when the parachute is open
velocity for Ping pong ball with parachute = 9m/s
velocity for Soccer ball with parachute = 15m/s
velocity for Golf ball with parachute =24m/s
velocity for Watermelon with parachute = 25m/s
so weight of an object doesn’t really realted how fast it falls with a parachute
Answer:
<h2>The answer is 5 s</h2>
Explanation:
The time taken can be found by using the formula
d is the distance
v is the velocity
From the question we have
We have the final answer as
<h3>5 s</h3>
Hope this helps you
