Question

question 15 1 pts when a cannonball is fired from a cannon, which undergoes the greater acceleration? the recoiling cannon the cannonball both the same question 16 1 pts neglecting air resistance, once a tossed ball leaves your hand only the force due to gravity acts on it. no further forces act on it. your tossing force remains while the ball goes upward. your tossing force remains until it comes to a stop. inertia becomes the force acting on it.

Explanation:

For Question 15, according to Newton's second - law $F = ma$. The force on the cannonball and the recoiling cannon is a pair of action - reaction forces (Newton's third law), so $F_{cannonball}=F_{cannon}$. Since the mass of the cannonball $m_{cannonball}$ is much smaller than the mass of the cannon $m_{cannon}$, from $a=\frac{F}{m}$, the cannonball has a greater acceleration.
For Question 16, according to Newton's first law, once the ball leaves the hand, neglecting air resistance, the only non - zero force acting on it is the gravitational force.

Answer:

Question 15: B. the cannonball
Question 16: A. only the force due to gravity acts on it.
