Answer:
Object A
Explanation:
The object that would make you feel worse if you're hit by it is the object possessing the highest momentum. Thus, we need to find the momentum of the two objects.
Momentum of an object is the product of its mass and that of it's velocity. Momentum is given by the formula
P = M * V, where
P = momentum
M = mass of the object
V = velocity of the object
Now, solving for object A, we have
P(a) = 1.1 * 10.2
P(a) = 11.22 kgm/s
And then, solving for object B, we have
P(b) = 2 * 5
P(b) = 10 kgm/s
The object when the highest momentum is object A, and thus would make you feel worse when hit by it
Answer:A:The track pushes back on Clinton's shoe with the same force.
Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.
Answer:
<h3>The answer is 0.59 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>0.59 m/s²</h3>
Hope this helps you
Answer:
129.6 seconds
Explanation:
Given that :
α = 0.0002°c-1
θ1 = 20°C
θ2 = 5°C
Time t = one day ; Converting to seconds ; number of seconds in a day ; (24 * 60 * 60) = 86400 seconds
Let dT= change in time
Using the relation :
dT = 0.5* α * dθ * t
dθ = (20 - 5) = 15°C
dT = 0.5 * 0.0002 * 15 * 86400
dT = 129.6 seconds
