Note that the coordinate system is givenwith +y pointed in the upwards direction. Holding the parcel, the drone takes off moving straight upwith a velocity of 8.40. m/s. Note that, as usual, y = 0 at the ground.After 8.00 s, the drone accidentally releases the parcel! The parcel is in "freefall" immediately after it isreleased, as defined in Lecture 7. Assume that the magnitude of the acceleration, g = 9.81 m/s?, and thatthe drone continues with the same velocity after releasing the parcel. Ignore the effects of air-resistance.

In the standing broad jump, one squats and then pushesoff with the legs to see how far one can jump. Suppose theextension of the legs from the crouch position is 0.600 m andthe acceleration achieved from this position is 1.25 times theacceleration due to gravity, g . How far can they jump? Stateyour assumptions. (Increased range can be achieved byswinging the arms in the direction of the jump.)

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 roughly the speed of the Space Shuttle in a low Earth orbit when it was operational, or any satellite in a low Earth orbit. These and other aspects of orbital motion, such as Earth’s rotation, are covered in greater depth in Gravitation. Figure 4.17 Projectile to satellite. In each case shown here, a projectile is launched from a very high tower to avoid air resistance. With increasing initial speed, the range increases and becomes longer than t would be on level ground because Earth curves away beneath its path. With a speed of 8000 m/s, orbit is achieved.
