Consider the motion of a bullet that is fired from a rifle 2 m above the ground in a northeast direction. The initial velocity of the bullet is (300, 300, 0). Assume the x-axis points east, the y-axis points north, the positive z-axis is vertical (opposite g), the ground is horizontal, and only the gravitational force acts on the object. a. Find the velocity and position vectors for $t \ge 0$. b. Make a sketch of the trajectory. c. Determine the time of flight and range of the bullet. d. Determine the maximum height of the bullet. a. The velocity vector is $v(t) = ? ? ?$. (Simplify your answers. Use integers or decimals for any numbers in the expressions.)

Step 1
All force acts on the object: This means that there is a force acting on the bullet, which is causing it to move. We need to know the magnitude and direction of this force to determine the trajectory of the bullet. Show more…

A baseball of mass m, initially at rest, is struck by a bat so that it acquires a speed v. Let t represent the duration of the collision between the bat and the ball. Which one of the following expressions determines the magnitude of the average force exerted on the ball? A) (1/2)mv^2 B) mv/t C) (1/2)mv^2t D) mt^2/(2v) E) mvt

Object 1 moves with an initial speed of $v_{0}$ toward Object $2,$ which has a mass half that of Object $1 .$ If the final speed of both objects after colliding is $0,$ what must have been the initial speed of Object 2 (assuming no external forces)? (A) $v_{0}$ (B) 2$v_{\mathrm{o}}$ (C) $\frac{1}{2} v_{0}$ (D) 4$v_{0}$
