First, write down the information given and the change units if necessary (we must have similar units to operate on).
Initial speed, u = 36 km/h = 10 m/s
Final speed, v = 72 km/h = 20 m/s
Distance, s = 100 m
We know that
Now, we substitute v, u, and a in the formula

Answer:
Explanation:
given,
mass = 2.2 kg
altitude(r₀) = (70 j) m
speed = 30 m/s
m_a = 0.77 kg
m_b =1.43 kg
part A strike ground (r_a)= (80 i) m
t = 6 s
r = 63.6 j m
by conservation of energy
Answer:
stress = 50MPa
Explanation:
given data:
Length of strain guage is 5mm
displacement
stress due to displacement in structural steel can be determined by using following relation
where E is young's modulus of elasticity
E for steel is 200 GPa
stress = 50MPa
Answer:
Resolving Power=625000
Explanation:
See attached picture.
