Answer:
The correct equation for calculating force is change in momentum divided by time. So 10 kg m/s divided by 3 s is 3.3 newtons (N
Explanation:
Since 1m/s=3.6 km/h, we can conclude that 10.0m/s = 36 km/h
The speed of an object can be determined from the distance vs time graph.
You know that speed = distance/time
in the graph, distance/time = slope of the curve.
So SPEED IS GIVEN BY THE SLOPE of the curve in the graph.
● If the distance vs time curve is a straight line, parallel to time axis(x-axis), slope is 0. That means speed is 0. So the object is at rest.
● If the distance vs time curve is a straight line, with some non-zero slope; That means speed is nonzero and constant. So the object is in uniform motion.
● If the distance vs time curve is a curved, the slope is changing. That means speed is changing. So the object is in an accelerated motion.

Explanation:
This is a knitting skill that involves different colour patterns. Each color has a yarn for it. However, wood cut in shapes can also be filled with different colour patterns too.
Answer:
Decease the mass
Increase the force applied
Explanation:
To increase the acceleration of the shopping cart, Brielle should reduce the load inside her cart.
According to Newton's second law of motion;
Force = mass x acceleration
Now, mass is indirectly proportional to the acceleration. The more the mass, the lower the acceleration a body will generate.
Lighter bodies moves with a faster acceleration.
In this case the force applied is constant.
If the force applied is also, increased the acceleration of the body will increase also.
