Answer:
Fcoso-f =ma. F= ma 15 = 4.5 a then get acceleration. Fcoso- umg = ma then get friction
Search Results<span>Use BFS to determine the length of the shortest v-w-path. Then use DFS to find thenumber of the v-w-shortest paths such that two nodes are connected and the length of path equals to the output of BFS. But the running time of this plan is O(m+n)+O(m+n). Also I've tried to modify the Dijkstra algorithm.</span>
PE = mgh
so (75kg)(9.8m/s2)(100m) = 73,500 Joules
KE = 1/2 m * v^2
so (1/2)(75kg)(60m/s)^2 = 135,000 Joules
ME = 208,500 Joules
Answer:
A)F
B)F
C)T
Explanation:
A)
This is not always true that the product of the two vector's always non-negative .It may be positive or negative.
That is why this statement is false.
B)
The unit vectors in three perpendicular direction is i ,j and k.
We know that for unit vectors
i.i=j.j=k.k= 1
i .j= j.k=k.i=0
Therefore only parallel component of the force will contribute in the integral part instead of perpendicular component of the force.
That is why this statement is false.
C)
This statement is True.
A)F
B)F
C)T
