When given a particle’s position along the x-axis is described by the function x(t) = A t + B t2, where t is in seconds, x is in meters, and the constants A and B are given below. By given the variables below A = -3.6 m/s B = 3.5 m/s2   What would the expressions be, in terms of A, B, and t for the velocity of the particle as a function of time??

Tom Cogwagee Longboat, of the Six Nations of the Grand River, is one of Ontario's best known distance runners. In 1907, he set a new Boston Marathon record, beating all of the previous decade's champions by almost 5 minutes! If he ran the 39.2 km course in 2 hours, 24 minutes and 24 seconds, what was his speed? HINT: we'll need our units to be metres per second - what do you need to convert in the question? 0.221 m/s O 0.272 m/s O 4.52 m/s O 17.5 m/s

The picture shows the wingspan for a cardinal and for an Andean condor. What formula explains why the cardinal beats the wings faster than the condor? 300 cm | 30 cm Cardinal Andean condor O A. 1 = mr? O B. W = 0/t OC.I= Frsine O D. T= I-a

Help, I think the answer is the 5th choice, but I am not sure.

A woman stands at the edge of a cliff and throws a rock horizontally over the edge with a speed of v, = 19.5 m/s. The rock leaves her hand at a height of h = 49.0 m above level ground at the bottom of the cliff, as shown in the figure. Note the coordinate system in the figure, where the origin is at the bottom of the cliff, directly below where the rock leaves the hand. (a) What are the coordinates of the initial position of the rock? (Enter your answers in m.) m Yo = (b) What are the components of the initial velocity? (Enter your answers in m/s.) Vox = m/s Voy m/s

Let your character move in a constant acceleration (a + b / 2, -a-b) along the (a,b) direction with a velocity of (a+b, a-b). If the initial position of the character is at (a2b2, ab), where will the character be located after 2a + 3b + 4ab time units.  a = 5 b = 2 Solve using the following equation below

The magnitude of a particle's velocity is observed to vary with time according to the equation: |v = Bt where Bis a positive constant. What are the units of B? т S m Om: s? O m· .3 m

Problem 1 - Unit Conversions A plane moves with speed v = 400 km/h; rewrite v in m/s. The density of iron is approximately p = 7.8 g/cm; what is the density of iron in kg/m? Problem 2 - Velocity and Acceleration A point particle moves along the r axis, and its position as a function time is given by the equation z(t) = At² – B ,
