A 250 kg cannon is at rest. A 4 kg shot is loaded into the cannon. When the cannon is fired, the cannon recoils backwards with a velocity of 10.0 m/s. What is the velocity of the shot?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

This is the substance(s) formed in a chemical reaction.

What is a good example of instantaneous speed
