Calculate the acceleration of a galloping horse going from 2 m/s to 12 m/s in 2 seconds. a) 5 m/s/s b) -5 m/s/s c) 0.2 m/s/s

Kiloleter, mega leterhope this !

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.

The object needs to be bigger than you, or (most people would say) you’d be attracting it. no matter how small an object is, if it has mass, it has gravity.
