I am a little confused on Newtons Seconds Law in Two dimensions. I know that when acceleration is zero that the net force in both the x and y-directions becomes zero. Is that because when acceleration is zero there's no net force?
A baseball player throws a 0.2 kg ball (Ball A) from the top of a 10 m tall hill with a velocity of 40 m/s. Suppose that another ball (Ball B) with identical mass was dropped, not thrown, from the same height at the same time the first ball was thrown. Which ball hits the ground first? Explain Suppose another baseball player throws a 0.5-kg ball (Ball C), also at 40 m/s, at the same time, which ball will hit the ground first? Explain.
A student is performing a series of experiments where he hits two toy cars together and records the initial and final velocities of each. Using the data he collected below, how does the total momentum before the cars hit compare to the total momentum after?(answer choices in the 2nd screenshot)

Integrated Concepts A large rocket has a mass of 2.00106 kg at takeoff, and its engines produce a thrust of 3.50107 N. (a) Find its initial acceleration if it takes off vertically. (b) How long does it take to reach a velocity of 120 km/h straight up, assuming constant mass and thrust? (c) In reality, the mass of a rocket decreases significantly as its fuel is consumed. Describe qualitatively how this affects the acceleration and time for this motion.
To calculate the momentum of an object, which properties of an object do you need to know?
In Section 2.4, we computed the force needed to accelerate a 1,000-kg car from 0 to 27 m/s in 10 s. Compute the force using the alternate form of Newton’s second law. The change in momentum is the car’s momentum when traveling 27 m/s minus its momentum when going 0 m/s.
Integrated Concepts When starting a foot race, a 70.0-kg sprinter exerts an average force of 650 N backward on the ground for 0.800 s. (a) What is his final speed? (b) How far does he travel?
