Constant Acceleration

1

A ball is dropped from rest. What is its final velocity after 10 seconds? (Take g = 10 m/s²)

2

A car starts from rest. What is its final velocity after 10 seconds if it moves with a uniform acceleration of 10 m/s²?

3

A ball is thrown vertically downward with an initial velocity of 10 m/s. What is its final velocity after 10 seconds? (Take g = 10 m/s²)

4

A ball is thrown vertically upward with an initial velocity of 100 m/s. What is its velocity after 10 seconds? (Take g = 10 m/s²)

5

A car is moving with a constant velocity of 100 m/s. Suddenly, a damaged road is observed and the driver applies the brakes. If the car undergoes a retardation of 10 m/s² for 10 seconds, what is the final velocity of the car?

Explanation

Initial velocity, u = 100 m/s

Retardation = 10 m/s²

Therefore, acceleration a = -10 m/s²

Time, t = 10 s

Using v = u + at

v = 100 + (-10 × 10)

v = 100 - 100

v = 0 m/s

6

A ball is dropped from rest. If its final velocity is 100 m/s, how much time does it take to reach this velocity? (Take g = 10 m/s²)

7

A car starts from rest and reaches a velocity of 100 m/s. If its acceleration is 10 m/s², how much time does it take?

8

A ball reaches the ground in 10 seconds with a final velocity of 100 m/s. What was its initial velocity? (Take g = 10 m/s² and downward as positive)

9

A ball reaches the ground in 5 seconds with a final velocity of 100 m/s. What was its initial velocity? (Take g = 10 m/s² and downward as positive)
