A drop hammer weighing 40 kN is dropped freely and drives a concrete pile 150 mm into the ground. The velocity of the drop hammer at impact is 6 m/s. What is the average resistance of the soil in kN?

What will be the impact on the velocity of an object if it falls with constant acceleration?

Which statement among the following is the correct information to calculate speed and velocity?

1. Both require distance and velocity also requires time

2. Both require displacement and time

3. Both require time but velocity requires displacement and speed requires distance

4. Both require distance and time

A ball is thrown into the air with an initial upward velocity of 40 feet/seconds. If the height is given by the function h = 16 t2- 20 t where ‘t’ is the time in seconds then find out the time for the ball to hit the ground.
