A resting object starts accelerating down a straight track. It accelerates at 2 m/s squared for 6.5 seconds, then and 8 m/s squared for 9.25 seconds, and finally at 4 m/s squared for 4.75 seconds. What is the objects final velocity

106 m /s

Explanation:

v = u + at

v is final , u is initial , a is acceleration and t is time .

velocity after initial 6.5 s

v = 0 + 2 x 6.5 = 13 m /s

This becomes initial velocity for 9.25 s stretch .

velocity after next 9.5 s

v = 13+ 8 x 9.25

= 87 m /s

This becomes initial velocity for 4.75 s stretch .

Final velocity after next 4.75 s

v = 87 + 4 x 4.75

= 106 m /s

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
