Sir George’s acceleration has a magnitude of 0.213m/s^2, while Sir Alfred’s has a magnitude of 0.267 m/s^2. Relative to Sir Georges starting point, where do the knights collide?
On a spacecraft two engines fire for a time of 532 s. One gives the craft an acceleration in the x direction of ax = 4.92 m/s2, while the other produces an acceleration in the y direction of ay = 7.16 m/s2. At the end of the firing period, the craft has velocity components of vx = 3743 m/s and vy = 4808 m/s. Calculate the magnitude of the initial velocity.
A projectile is fired from the origin (at y = 0 m) as shown in the figure. The initial velocity components are V0x = 280 m/s and V0y = 44 m/s.
