Question 8 The velocity equations valt), vb(t), vc(t), and up(t) in (km/hr) of four cars A, B, C, and D, respectively are moving along a straight line and given by, VA(T) = arctan(81) UB(l) = In(91) vo(t) = e-71 Up(l) = V8 +12 Which of these cars travelled further during the time interval (12,14] (A) Car A (B) Car B. (C) Car C (D) Car D Your answer 4. 10 Points Determine concavity of the following. Find X-values where the...
06 Determine the relative velocity of particle B with respect to particle A A) (48i30j) km/h B) (-48i+30j ) km/h C) (48i 30j ) km/h D) (-48i -30j ) km/h B VB=100 km/h 30° A VA-60 km/h 2. If theta equals 90° and A and B start moving from the same point, what is the magnitude of TBIA at t 5 s? A) 20 ft C) 18 ft B) 15 ft VB= 4 ft/s D) 25 ft A =3 ft/s...
Please show all work with an explanation. Two highways intersect at right angles. From out point of view, Car A on one highway is 0.5 km from the intersection and is moving toward it at 96 km/hr, while car B on the other highway is 1 km from the intersection and is moving away from it at 88 km/hr. We would therefore call the position and velocity of car A to us to be Position: ?⃗? ?? ?? = (0.5...
If a is acceleration, v is velocity, x is position, and t is time, then check the validity (wrong or correct) of the following equations using dimensional analysis: a) t2 = 2x/a b) t = x/v c) a = v/x d) v = a/t ALSO , The term 1/2 PV^2 rv2 occurs in Bernoulli’s equation in Chapter 15, with P being the density of a fluid and v its speed. Find the dimensions of 1/2 PV^2 Thank you in advance...
