Answer:
The acceleration of the drone is 2.6 m/s²
Step-by-step explanation:
The acceleration is the rate at which the speed changes over time, therefore to solve this question we must divide the change of speed by the elapsed time in order to find the accelaration of the drone in that period. We have:
a = (Vf - Vi)/dt
Where a is the acceleration, Vf is the final velocity, Vi is the initial velocity and dt is the elapsed time. We have:
a = (51 - 38)/5 = 2.6 m/s²
Answer: <em><u>4.</u></em> This is because 1 and 1/5 = 1.2 and 3/10 = 0.3 and 1.2 divided by 0.3 = 4. That's because 1.2 can be split into 4 equal groups and each group has 0.3.
(6*8) is where the parentheses should go
X=0 y=-2
y=0 x=4
The shortest distance has to be the perp bisector from origin to the midpoint of the line.
midpoint =(2,-1) and distance from the (0,0) origin is sqrt(5) hence, sqrt(5).
