Here it is: A painter loses his balance and falls from the top step of a two-step step stool, but still manages to land on his feet.
Estimate the magnitude ?avg of his average acceleration when he hits the ground, assuming his knees don't flex. ?avg = ___ m/s2
Estimate the magnitude ?avg of his average acceleration if his knees do flex as he hits the ground. ?avg = ___ m/s2

A 76 kg man drops to a concrete patio from a window only 0.55 m above the patio. He neglects to bend his knees on landing, taking 2.0 cm to stop. (a) What is his average acceleration from when his feet first touch the patio to when he stops? m/s2 (b) What is the magnitude of the average stopping force? kN

While unrealistic, we will examine the forces on a leg when one falls from a height by approximating the leg as a uniform cylinder of bone with a diameter of 2.3 cm and ignoring any shear forces. Human bone can be compressed with approximately 1.7 × 108 N/m2 before breaking. A man with a mass of 70 kg falls from a height of 7 m. Assume his acceleration once he hits the ground is constant. For these calculations, g =...

1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...

you are given 4 vectors with equal magnitudes. under what conditions will their sum be zero? if a vector has an equal, positive x and y components, what are the angles it makes with the axes? A superhero jumped horizontally from a 31 m high rooftop to the ground immediately after he spotted a child walking towards a busy street all alone. Fortunately, he lands on the street just next to the child in 2.5s and the child is rescued!...

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...

just now i sent this questions.
this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
the heat transfer coefficient, h. please help me. thank you.
this pic is a note on constant surface temperature.
