Question

What's the relationship between acceleration and speed?

anonymous · Answer

Acceleration is the time rate of change of speed.

anonymous · Answer

so 5.0 m/s^2 to m/s? I am not sure

anonymous · Answer

by multiplying it by time, which has units of (s) so (m/s^2) * (s) = (m/s).

anonymous · Answer

so 5.0m/s^2 (3600s)?

anonymous · Answer

Well, we don't want an hour of accelerating to happen, the problem says we want the speed after they've been accelerating for 1.7 sec

anonymous · Answer

so it's just 5 (1.7)?
