The helicopter in the drawing is moving horizontally to the right at a constant velocity
The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W = 55300 N. The lift force L generated by the rotating blade makes an angle of 21.0° with respect to the vertical.(a) What is the magnitude of the lift force? N(b) Determine the magnitude of the air resistance R that opposes the motion. N

A ball of mass m moving with velocity v_i_vec strikes a vertical
wall. The angle between the ball's initial velocity vector and the
wall is theta_i as shown on the diagram, which depicts the
situation as seen from above. The duration of the collision between
the ball and the wall is Deltat, and this collision is completely
elastic. Friction is negligible, so the ball does not start
spinning. In this idealized collision, the force exerted on the
ball by the...

3.) A jet plane is flying with a constant speed along a straight line at an angle of 30° above the horizontal. The plane has a weight W of magnitude 86500 N and its engines provide a forward thrust T of magnitude 103000 N. In addition, the lift force L (directed upwards perpendicular to the wings) and the force R of air resistance (directed opposite the motion) act on the plane. Find L and R. [L = 74900 N; R=...

A ball of mass m moving with velocity v⃗ i strikes a vertical wall as shown in (Figure 1) . The angle between the ball's initial velocity vector and the wall is θi as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is Δt, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the...

2) Rita is in an elevator that is moving at a constant velocity downward. If the elevator now experiences an acceleration so that it speeds up, the normal force Rita experiences A) becomes greater than her weight. B) remains equal to her weight. C) becomes less than her weight, but not equal to zero. D) becomes zero. E) cannot be determined without more information. 11) A rope connects object A (mass 4m) with object B (mass m).

4. Luay is running with a horizontal velocity, along level ground. While running, he encounters a 2.51 m vine of negligible mass; the vine was hanging vertically from a tall tree limb and the end of the vine is directly level with his center of mass. Luay decides to grab the vine and swing, because he loves experiencing uniform circular motion. At the maximum height, Luay takes mental note that the angle the vine makes with...

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...
