Problem 3P

What is the instantaneous velocity of a freely falling object 10 s after it is released from a position of rest? What is its average velocity during this 10-s interval? How far will it fall during this time?

Step-by-Step Solution:

Answers: Step 1: Here ,we have calculate Instantaneous velocity= Average velocity = Total distance travelled= Given: Time = 10 seconds Acceleration due to gravity = 9.8 m/s ( as the object is falling from a certain) initial velocity(u) = 0 Step 2: We know the three equations of motion. V= u + at………….(1) 2 S= ut +½ at ……..(2) V = u + 2as ……..(3) Here = V is the final velocity u is the initial velocity S is the displacement t is the time taken a is acceleration or acceleration due to gravity (g) Step 3: To calculate instantaneous velocity, we can use equation (1) of motion as above, Substituting value of g or a = 9.8 m/s and initial velocity(object at rest) (u) = 0 V = u + at …………..(1) 2 There V= 0 + 9.8 m/s x 10s V= 98 m/s Therefore the instantaneous velocity of the falling object 98 m/s,
