One object is thrown vertically upward with an initial velocity of 100 m/s and another object with an initial velocity of 10 m/s. The maximum height reached by the first object will be that of the other:
Correct answer: C. 100 times
- A. 10 times
- B. 1000 times
- C. 100 times
- D. 10000 times
Explanation
To determine the maximum height reached by each object, we use the formula for the maximum height in projectile motion: h = v2/2g. Here, v is the initial velocity, and g is the acceleration due to gravity, which is approximately 10 m/s2 for simplicity.For the first object with an initial velocity of 100 m/s: h1 = 1002/[2(10)] = 10000/20 = 500 m.For the second object with an initial velocity of 10 m/s: h2 = 102/[2(10)] = 100/20 = 5 m.Thus, the maximum height reached by the first object is 500/5 = 100 times that of the second object.Options A, B, and D are incorrect because they do not match the calculated factor of 100 times, which is the result derived from the formula.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
