An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. determine the distance traveled before takeoff.

In a physics equation, given a constant acceleration (a, the change in velocity of an object) and time involved (t), you can figure out the distance (S) traveled by using this formula :

S = 1/2 x acceleration(a) x times(t)^2

So in this case, we can compute the distance by supplying the available data into the equation,...

S = 1/2 x 3.2 m/s2 x (32.8s)^2

S = 1721m

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
