A body is dropped from certain height and falls freely, its velocity after 5 seconds will be:
Correct answer: E. 49m/s
- A. 94m/s
- B. 9.4m/s
- C. 0.49m/s
- D. 4.9m/s
- E. 49m/s
Explanation
To determine the velocity of a body that falls freely, we can use the equation for free fall: v = gt Where: v is the final velocity, g is the acceleration due to gravity (approximately 9.8 m/s²), and t is the time. In this case, the body has fallen for 5 seconds, so we can substitute the values into the equation: v = (9.8 m/s²)(5 s) = 49 m/s Therefore, the correct answer is option (e): 49 m/s. As it is numerical only one option E is correct.

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.
