If the cart's mass is 4.2 kg the applied force is 12.6 N and the friction force is 5.4 N find the cart's acceleration. Express your answer to two significant figures and include the appropriate units.?

the net force is 12.6 - 5.4 = 7.2N; since F = ma where m is 4.2 kg thena = F/m = 7.2/4.2 =1.71 meters per second per second.A Newton is 1 kg meter/sec/sec)

What unit do you use to express free-fall acceleration?
the unit of acceleration is unit length per squared unit time, usually m/s2.
What is the most appropriate SI unit to express the speed of a cyclist in the last leg of a 10 km race?
SI unit for (average speed) = metres per second.
How centripetal acceleration express in terms of time period and frequency?
Here are two commonly used formulae for centripetal acceleration: a = v2/r a = omega2r The second seems closest to what you are looking for. Omega (lower case omega) is the angular speed, in radians/second. It is equal to the frequency (revolutions/second) times (2 x pi). Thus, you can replace: a = (2 x pi x f)2 x r = 4pi2f2r
What is the unit used to express frequency?
Hertz

What units express acceleration?
(any unit of speed) / (any unit of time)OR(any unit of length or distance) / (any unit of time, squared)is a perfectly appropriate unit of acceleration.If you're dealing with acceleration as a vector, then a direction also needs to go with it.
