Task 4: A body thrown horizontally from a height of 20 m fell 20 m from the point of ejection. Calculate the initial and final velocity of the body!

Show solution:

Task 5: The body is thrown in a horizontal direction. How to increase the initial speed of the body:

a) So that the flight distance increases 5 times;

b) Ejection height above the ground so that the flight distance increases 4 times?

Task 6: A body is thrown with a speed of 60 m/s in a direction that makes an angle of 30 degrees with the horizon.

a) Calculate the highest height that the body reaches in flight;

b) Flight distance;

c) Flight duration;

d) The angle at which the body must be thrown to the horizon (with the given velocity of ejection) so that the flight distance is the same with maximum flight height!
