Answer:
Yes
Explanation:
Accerelation is measured by change in velocity. So naturally, if an object is slowing down, its velocity is decreasing so acceleration is negative. If it is speeding up velocity is increasing so positive acceleration.
(Velocity final - Velocity initial)/t
Note that this does not apply only to gravity, but to all linear accelerations
A lot of it is all experimental as long as you are taking caution of safety while doing it. I personally would use copper wiring mainly for the fact that it is a nice conductor. For the wrap around the wiring i usually would use black or red electrical tape just because it has very nice insulator properties and is safe to use.
Answer:
0.25m
Explanation:
Using the expression that relates the angular velocity(w) and the linear velocity (v).
v= wr where;
w is the angular speed= 128rad/s
v is the linear speed = 32m/s
r is the radius
r = v/w
r = 32/128
r = 0.25m
The radius of the blade is 0.25m
Answer:
The acceleration will decrease/reduce
Explanation:
Newton in his second law of motion states that the acceleration of an object is dependent on the force and mass applied on the object. Using the equation as follows:
F = m × a
Where;
F = force (N)
m = mass (kg)
a = acceleration (m/s²)
Acceleration (a) is directly proportional to the force (F) applied but inversely proportional to the mass (m).
According to this question, a friend drops 50 pounds of dog food into a cart being pushed with speed. This means that the mass/weight of the cart was increased. Since the acceleration is inversely proportional to the mass of an object, this means that the acceleration of the cart will DECREASE/REDUCE as the mass increases.
