On a body of mass m that is in a smooth horizontal plane began to act at
the time t = 0 a force that depends on time according to the law F = ct,
where c is a constant. The direction of this force constantly forms an
angle a with the horizontal direction, calculate:
a) The velocity of the body at the moment of separation from the plane
b) The body's journey at this moment.

2) When construction of the Tillery Hydroelectric Plant was begun in 1926, it was realized that the reservoir resulting from the construction of the dam would flood the Swift Island Bridge across the Pee Dee River, and led to the construction of the present Swift Island Bridge. The US Army Air Corp decided to test aerial bombardment against the old bridge using the Keystone LB-5 light bomber. Assume an LB-5 approaches the bridge at a 90° angle to the span at 40 m/, and releases its bomb from an altitude of 1 800 m. Ignoring air resistance and crosswinds, How far from the bridge must the bomb be released to hit the bridge on the centerline? b. How long does it take the bomb to hit the bridge after being released? What is the terminal velocity of the bomb? a. с.
