Product description
1. The boat moves perpendicular to the river bank at the speed of 18 km / h. The river takes down her while crossing 150 m. The width of the river 450 m. Find the crossing and the flow velocity.
2. From the roof fall one after the other two drops. After 3 seconds after the start of the fall of the second drop of the distance between the drops become equal to 30 m. What time interval drops began to fall?
3. The plane, flying at an altitude of 500 meters at a speed of 324 km / h, drops a bomb. Air resistance decreases range bombs twice. At some distance from the target is necessary to drop the bomb to hit it?
4. The body slip uniformly on an inclined plane with an inclination angle of 40 °. To determine the coefficient of friction on the plane.
5. The ball weighing 1 kg hits a vertical stack. Its speed before impact is 10 m / s and is directed at an angle of 30 ° to the plane of the wall. Find the momentum of force transmitted on impact wall, and the average force of impact. Impact duration is 1.1 seconds.
6. Motor boat moves at a speed of v = 18 km / h. The motor boat has an output N = 1 kW. Considering that half of the capacity (k = 1/2) is spent on overcoming the force of water resistance Fc, find the value of this force.
