Answer:
I believe it would be D).3 x 10 to the 9th power
Explanation:
Answer:
Your answer should be 2. Short
Explanation:
From my research, the following image is used for the problem. For each segment, the displacement can be obtained by looking for the area under the segment.
Part A:
displacement = (1/2)*10*2 = 10m
Part B:
displacement = [(1/2)*4*5] + (5*2) = 20m
<span>Part C:
</span>
displacement = [(1/2)*4*10] + (2*10) = 40m
Using the impulse-momentum theorem and taking this down as positive, we will get:
FΔt = Δp
F = Δp / Δt
= m(v - v₀) / t
= 0.056kg [13m/s - (- 20m/s) / 0.00125s
= 1478.4 N when properly rounded off is the answer we are looking for in this problem.
Answer
Hi,
The forces are; weight (gravity), Normal/centripetal force and friction. Force due to gravity is constant where as friction and centripetal are not.
Explanation
Weight is constant, given by the force of gravity on the object. The centripetal force is a function of the angles occurring between the velocity vector and the weight vector that is at right angle with the perpendicular line drawn from the surface. Friction is a function of the centripetal force thus it also varies.
Hope this helps!
