Since the biker is moving at constant speed
so we will have

here we know that

time = 4 second
now we have

now at the top point it feels free fall
so it is




so height of the bike at the top is same as diameter


Yes it will hurt on falling from this height
10/9
Explanation:
option 2 is the correct answer
Answer:
Fp = 36 N
Fq = 58 N
Explanation:
Let the left end be the reference end with string p closest to it.
Let CCW moments be positive
Sum moments about p to zero
1(9.8)[2 - 1] + Fq[6 - 2] - 5(9.8)[8/2 - 2] - 1.5(9.8)[5 - 2] - 2(9.8)[7 - 2] = 0
Fq[4] = 23.5(9.8)
Fq = 57.575 ≈ 58 N
Sum moments about q to zero
1(9.8)[6 - 1] - Fp[6 - 2] + 5(9.8)[6 - 8/2] + 1.5(9.8)[6 - 5] - 2(9.8)[7 - 6] = 0
Fp = 35.525 N
or
Sum vertical forces to zero
Fp + 57.575 - (9.8)(1 + 1.5 + 2 + 5) = 0
Fp = 35.525 ≈ 36 N
Answer:
The dilatation is 3 because the <em>separation </em>between the dilatation center C and P grows by that factor of 3.
Explanation:
- Between C and P, the separation is |5-1| = 4 in x-axis and |2-4| = 2 in y-axis
- Between C and P', the separation is |13-1| = 12 in x-axis and |-2-4| = 6 in y-axis.
Comparing the separation on each direction, 12/4 = 3 and 6/2 = 3. Therefore, that's the dilatation value.
Alternatively, by computing the distances between the points
