A small, battery-powered, electric motorboat that can travel at a speed of 1.80 m/s in still water is operating in a river with a flow speed of 1.35 m/s. For each of the following two cases, determine the requested information for a river that is 220 m wide. (a) Case 1: when the boat is pointed straight across the river, determine the speed Vbl of the boat as viewed by someone on land, the distance d the boat is swept downstream before reaching the other side, and the time t it takes the boat to make the crossing. Vbl = m/s d = t1 = (b) Case 2: if the boat operator wants to land the boat straight across the river from the launch site, determine the speed Vbl of the boat as viewed by someone on land, the angle ß upstream at which the boat should be pointed, and the time t2 it takes the boat to make the crossing. Vbl = m/s ß = t2 = S

Assume that, at the initial instant to = 0, a particle is thrown with initial speed vo and with an initial angle θo, with respect to a direction parallel to the Earth's surface. In this way, in order to carry out an analytical study of its motion in a simpler way, consider a coordinate system xoy, with its origin at the particle's launch position, and with its positive x axis oriented in the direction of the horizontal motion of the particle and with its positive y-axis oriented vertically upward. In this sense, illustrate (make the force diagrams) the projectile launch, highlighting its main characteristics, and describe algebraically what is asked: a) The necessary hypotheses and their corresponding consequences so that there can be an ideal projectile launch. b) Time functions of the positions x(t) and y (t) and the velocity vy(t) of this particle.
Check Your Understanding If the two golf shots in Example 4.9 were bunched at the same speed, which shot would have the greatest range? When we speak of the range of a projectile on level ground, we assume R is very small compared with the circumference of Earth. If, however, the range is large, Earth curves away below the projectile and the acceleration resulting from gravity changes direction along the path. The range is larger than predicted by the range equation given earlier because the projectile has father to fail than it would on level ground, as shown in Figure 4.17, which is based on a drawing in Newton's Principia. If the initial speed is great enough, the projectile goes into orbit. Earth's surface drops every 8000 m. In 1 s an object falls 5 m without a resistance. Thus, if an object is given a horizontal velocity of 8000 m/s (or 18,000 mi/hr) near Earth's surface, it will go into orbit around the planet because, the surface continuously falls away from object Thu is…
