They hit the ground at the same time
Answer:
19372.29 N
Explanation:
Kinetic Energy of the man = Work done by the average resistive force of water.
mg(H+d) = F×d............................ Equation 1
where, m = mass of the woman, H = Height of the platform, d = depth of water reached, F = average resistive force exerted by water.
make F the subject of the equation,
F = mg(H+d)/d...................... Equation 2
Given: m = 65.0 kg, H = 10 m, d = 3.4 m, g = 9.8 m/s²
Substitute into equation 2
F = 65(9.8)(100+3.4)/3.4
F = 19372.29 N
Answer:
pressure = force/area
force = 200N
area = πr², π =3.142, r = 12 cm = 0.12 m
pressure = 200/3.142×(0.12)²
p = 200/3.142×0.24
p = 200/0.754
p = 265.25 Nm-¹ or 265.25 Pa
Answer:
Explanation:
Length of the conveyor belt is given as
time taken to cook one burger is given as
now we can find the speed of the belt as
Now we know that the distance between two burgers is given as 25 cm
now the production rate of burgers is given as
