Answer:
1283.20 kg
Explanation:
By Newton's Second Law, we know that F=ma.
a = 2.56m/s^2
F = 3285 N (1 N = 1kg*m/s^2)
F = ma -> m = F/a
m = (3285 N)/(2.56 m/s^2)
m = 1283.20 kg
Answer:
to find the displacement, or delta x (change in position) on a velocity graph, you can find the area under the line on the graph: between 1 and 8 seconds, the dog was going at 5m/s, so 5m/s x 8s=40m, for the second part, you have to find the area of both a triangle and a rectangle, so the rectangle would be 5m/s x 5s=25m and the area under the triangle would be (5m/s x 5s)/2=25m/2=12.5m -you divide by 2 because it's a triangle
-afterwards, you would add the area of the 2 sections together, so 40m+25m+12.5m=77.5m
Explanation:
Answer:
0.05 m/s (It normally stays the same if no outside forces interferes)
Explanation:
It is 0.05 because of you pay attention to the info, it will say that the momentum ”before” the 2 marbles collision is 0.05 m/s, so it is still 0.05 m/s.
