"After 64 seconds, ABOUT HALF of the brands of milk chocolate are LIKELY to melt and NONE of the brands of Dark Chocolate are likely to melt"
Answer:
time = 2.48 seconds
Step-by-step explanation:
Given data:
distance = 100 foot
Initial velocity = 0 <em>because it was held and being released.</em>
acceleration is gravitational force
<em>gravitational force in feet per second = 32.2 ft/s²</em>
<em>formula for distance is s = ut +(1/2)at² where s = distance , u = intial velocity , a = acceleration and t = time</em>
s = ut +(1/2)at²
100 = 0(t) + (1/2)(32.2)t²
100 = 16.2t²
100/16.2 = t²
therefore t = 2.484
t = 2.48 seconds (to 2 decimal places)
Answer:
The minimum amount of breaking strain the crane can handle is 6350 kg. (Since it is measured to 2 sig. figs, 6349 kg would round down to 6300 kg, hence the min. is 6350 kg.)
The maximum weight of each crate would be 94 kg. (Since it is measured to the nearest 10 kg, 95 kg would round up to 100 kg, hence the max. is 94 kg.)
Therefore, the greatest number of crates that can be safely lifted would be (6350/94) crates which is 67.5 crates, which rounded down is 67 crates.
All numbers are taken as integers in this answer.
