Acceleration = (change in speed) / (time for the change)

Change in speed = (42 - 35) = 7 m/s

Time for the change = 40 sec

Acceleration = (7 m/s) / (40sec) = 7/40 = <em>0.175 m/s²

An initially stationary object experiences an acceleration of 6 m/s2 for a time of 15 s. How far will it travel during that time
umka21 [38]

Answer:

Explanation:

s = s₀ + v₀t + ½at²

s = 0 + 0(15) + ½(6)(15²)

s = 675 m

Not sure what the free fall acceleration is needed for, but if the object is dropped from a high enough point, it will travel in 15 seconds

s = ½10(15²) = 2250 m  if air resistance is ignored

Amanda [17]

Answer:

30m/s^2

Explanation:

Acceleration=Final Velocity-Initial Velocity/Time

10m/s^2= Final Velocity-0m/s/3

30m/s^2= Final Velocity

Final Velocity=30m/s^2
