Taking the vertical component of the displacement
1.1 - 0.2 = 0.9 mile
The horizontal component of the displacement
-0.3 mile
The magnitude of the displacement is
√[ (0.9)² + (-0.3) ] = 0.95 mile
The direction is
θ = tan-1 (-0.3/0.9)
θ = 161.57 degrees.
Answer:B
Explanation:
Calculate speed using equation:V=S/t
S=980 km ------------ distance Boston-Detroit
t=2h --------------------- time
v=?
------------------------
V=S/t
V=980km/2h
V=490km/h
Answer:
1.47x10^11
Explanation:
young modulus = stress / strain
stress = force / area = 200x9.8 / 0.00004 = 49000000
strain = extension / length = 0.001 / 3 = 0.0003333
49 million / 0.0003333 = 1.47x10^11
