= A golf ball leaves the ground with an initial velocity VoVoxl+Voyf. The ball hits a vertical wall which is located a horizontal distance b from the point of projection. When the ball strikes the wall, it is at a height h above the ground and it is moving horizontally. Find an expression for b in terms of the components Vox and voy of the initial velocity. (Hint: find the flight time between launch and impact in terms of vox and Voy) Vo h →→→X b
The velocity of a 1.0 kg particle varies with time as = (8t)i + (3t2))+ (5)k where the units of the cartesian components are m/s and the time t is in seconds. What is the angle between the net force F acting on the particle and the linear momentum of the particle at t = 2 s? (Hint: dot product)
A pickup truck is traveling along a straight flat highway at a constant speed of 10 m/s measured relative to the ground. A person standing in the flatbed of the pickup truck throws a ball into the air at an angle of 60° above the horizontal as measured relative to the truck and in line with the highway. A second person who is standing on the ground nearby observes the ball to rise vertically. Take the positive direction of the x-axis to point horizontally in the direction of motion of the truck and the positive direction of the y-axis to point straight up from the ground. Find the velocity of the ball relative to the truck in unit vector notation.
