Determine the collision time and angle for two projectiles A bird of mass ml flies horizontally...
A 550.0 g bird is flying horizontally at 2.25 m/s, not paying much attention, when it suddenly flies into a stationary vertical bar, hitting it 25.0 cm below the top (Figure 1). The bar is uniform, 0.800 m long, has a mass of 1.50 kg kg, and is hinged at its base. The collision stuns the bird so that it just drops to the ground afterward (but soon recovers to fly happily away). PART A: What is the angular velocity...
1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...
PART A: An electron moves at 3.00×106 m/s through a region in which there is a magnetic field of unspecified direction and magnitude 7.50×10−2 T . A1: An electron moves at 3.00×106 m/s through a region in which there is a magnetic field of unspecified direction and magnitude 7.50×10−2 T . A2: What is the smallest possible magnitude of the force on the electron due to the magnetic field? Express your answer in newtons to the nearest integer. A3: If...
Example 4.3 A Bull's-Eye Every Time In a popular lecture demonstration, a projectile is fired at a target in such a way that the projectile leaves the gun at the same time the target is dropped from rest. Show that if the gun is initially aimed at the stationary target, the projectile hits the falling target as shown in figure (a). The velocity of the projectile (red arrows) changes in direction and magnitude, but its acceleration (purple arrows) remains constant....
