Jana Novotna of what is now the Czech Republic has the strongest serve among her fellow tennis players. In 1993, she sent the ball flying with a speed of 185 km/h. Suppose a tennis ball moving to the right at this speed hits a moveable target of unknown mass. After the one-dimensional, perfectly elastic collision, the tennis ball bounces to the left with a speed of 80.0 km/h. If the tennis ball's mass is 5.70 x 10-2 kg, what is the target's mass? (Hunt: Use the conservation of kinetic energy to solve for the second unknown quantity.)

We investigated a jet landing on an aircraft carrier. In a later maneuver,the jet comes in for a landing on solid ground with a speed of 95 m/s, and itsacceleration can have a maximum magnitude of 6.37 m/s2 as it comes to rest.(a) From the instant the jet touches the runway, what is the minimum time intervalneeded before it can come to rest?(b) Can this jet land on a small tropical island airport where the runway is 0.800 kmlong? Show your work using a calculation.
A team of jubliant engineering students, celebrating winning a designcompetition, fires their potato gun straight up into the air. (a) Assuming a quadratic airdrag on the potato with magnitude F (v) = mkv^2, and taking +y to be the upward direction,show that the potato speed varies with height above the ground according to the equations:
For a perfectly elastic collision, u1+v1=u2+v2, or alternatively, u2−u1=v1−v2. If object 2 is initially at rest, then u2=0. Then v1−v2=−u1. However, for a partially elastic collision the relative velocity after the collision will have a smaller magnitude than the relative velocity before the collision. We can express this mathematically as v1−v2=−ru1, where r (a number less than one) is called the coefficient of restitution. For some kinds of bodies, the coefficient r is a constant, independent of v1 and v2. Show that in this case the final kinetic energy of the motion relative to the center of mass is less than the initial kinetic energy of this motion by a factor of r2. Furthermore, derive expressions for v1 and v2 in terms of u1 and r.
An apple drops from the tree and falls freely. The apple is originally at rest a height 3 m above the top of the grass of a thick lawn, which is made of blades of grass of height 0.5 m. When the apple enters the grass, it slows down at a constant rate so that its speed is 0 m/s when it reaches ground level. a. Sketch the y-t, Vy-t, and Ay-t graphs for the motion of the apple
Scientists observe an approaching asteroid that is on a collision course with Earth. They devise a plan to launch a rocket that will collide with the asteroid inelastically and stop it. The mass of the asteroid is 7500 kg, and it is approaching Earth at 85 m/s. If the rocket has a mass of 900 kg, approximately what velocity must it have to completely stop the asteroid after collision?

You wish to put a 1000-kg satellite into a circular orbit 300 km above the earth’s surface. (a) What speed, period, and radial acceleration will it have? (b) How much work must be done to the satellite to put it in orbit? (c) How much additional work would have to be done to make the satellite escape the earth? In part (b) if we ignored the satellite’s initial kinetic energy due to the rotation of the earth. How much difference does this make? Suppose your personal spacecraft is in a low-altitude circular orbit around the earth. Air resistance from the outer regions of the atmosphere does negative work on the spacecraft, causing the orbital radius to decrease slightly. Does the speed of the spacecraft (i) remain the same, (ii) increase, or (iii)
