D the force of inertia keeps the spear going
zero,as the object is moving in a straight line with constant speed which the velocity is constant
both the objects would hit the ground at the same time because time of flight does not depend on the mass
Add Answer to:
According to Galileo, a thrown spear keeps moving after it has left the spear thrower's hand...

Question 2 According to Newton's Laws of Motion, if I throw a baseball in outer space - far from any other object- how will that ball move over time? (For the sake of this problem, let's neglect my mass) After the force of my hand no longer acts on the ball: Question 2 options: the ball will move forward, but it will gradually slow down and come to a stop once the force of my hand no longer acts on...

1) An object undergoes uniformly accelerated motion from point x1 = 6 m at time t1 = 3 s to point x2 = 47 m at time t2 = 7 s. (The direction of motion of the object does not change.) (a) If the magnitude of the instantaneous velocity at t1 is v1 = 2 m/s, what is the instantaneous velocity v2 at time t2? (b) Determine the magnitude of the instantaneous acceleration of the object at time t2. 2)...

Newton's Satellite Directions: Read the background information and complete the activity Newton's Thought Experiment In the seventeenth century, Sir Isaac Newton was studying the nature of motion and gravity. He formulated a thought experiment that would eventually become the basis of the development of satellites. Imagine an object is fired from a cannon horizontal to the plane of the earth. The projectile will travel in a horizontal direction and undergo projectile motion as gravity begins to pull the projectile downward....
