Question

1. Shown in the figure is the path (trajectory) of a particle during a time interval and its velocity
vector at an instant. The speed at this instant is 10 m/s. Determine the horizontal velocity
dx/dt of the particle at this instant.
y
30°
P
- X

Expert Solution

Step 1 To determine,

The horizontal velocity $\frac{dx}{dt}$ of the particle at this instant.

given,

$Speed at that instant (v) = 10 m \cdot s^{- 1} angle made with horizontal (θ) = 30^{o}$

An object slides along the inside of a vertical circular track and never loses contact with the track. As it slides upward it slows down, and as it slides downward it speeds up. It's not known whether it's moving clockwise or counterclockwise in the view shown. Match points A, B, C, and D with possible acceleration vectors at those points. Only one of the acceleration vectors shown is possible at each point. A с a B

A circus performer throws a knife at a bound stagehand who is tied to a post. The knife is thrown at an angle of 17.8° below the horizontal with an initial speed of 3.11 m/s. The knife hits the post between the stagehand's feet, a distance of 0.63 m vertically below where it was released. How far from the post was the performer when she threw the knife? Select one: a. 0.81 m cross out b. 0.38 m cross out c. 0.17 m cross out d. 0.77 m cross out e. 0.65 m cross out Your answer is incorrect. The correct answer is: 0.81 m
Lesson: Projectiles When there is air resistance present how to the velocity and acceleration vectors behave? O The acceleration vector is perpendicular to the trajectory and the velocity vector is at a tangent to it. O The acceleration changes throughout the flight with its x-component opposite the direction of motion. The velocity vector is at a tangent to the trajectory O The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory O The acceleration and velocity vectors are both constant magnitude but continually change direction.
