Here too when an object is dropped, we know the initial velocity is zero when in free fall. So V =g*t this implies V= 9.8 *5=49m/s..... do you get it?
Answer:
Explanation:
momentum = mv
m = 8 kg
v = 12 m/s
momentum = 8 * 12 = 96 kg m/s
6.71081mph(miles per hour) or 3m/s (meters per second)
Answer:
A quick way of describing density is to describe an object as heavy or light for its size. Pumice stone, unlike regular rock, does not sink in water because it has a low density. An ironwood branch is very dense and sinks in water.
Hope that helps. x
