Answer: 61.1 is the answer I wish this answer help you.
Answer:
C voltage
Explanation:
Voltage is the change in electric potential so basically current flows from high potential to low potential due to voltage.
Answer:
12.5 m/s
Explanation:
If the avg speed is 10 m/s we assume that the speed is constant and not fluctuating
If VT (Velocity*Time) is equal to speed at the end of the 4 seconds of accel. it is the top speed at the finish line
since the speed is 0 at the beginning of races, we will use V0= 0 m/s
So the avg velocity for those 4 seconds is (VT+V0) /2 = or 1/2 VT (for 40% of the race)
The avg velocity for the last 6 seconds is, of course, VT (for 60% of the race
hence
(1/2VT)(.4) + VT(.6) = 10 m/s
VT = 10/.8 = <u>12.5 m/s

Answer:
6600J
Explanation:
the formula for work is: W= F x d
F- force, d- distance
Explanation:
A projectile motion may be defined as that form of a motion that is experienced by an object or a particle which is projected near the surface of the Earth and the particle moves along the curved path subjected to gravity force only.
Thus a projectile motion is always acted upon by a constant acceleration due to gravity in the down ward direction.
In the context, Quinn shoots two particle x and y from his sling shot and he observes that both his projectiles travels in a parabola curve in the air. Both the object x and y touches the ground a distance apart from him which is known as the range and it depends upon the velocity of the projectile. Both the projectile reaches a maximum height and then drop on the ground in a parabola shape.
