We can use the textbook results for head-on elastic collisions to analyze the recoil of the earth when a ball bounces off a wall embedded in the earth. suppose a professional baseball pitcher hurls a baseball ( 155 grams = 0.155 kg) with a speed of 100 miles per hour ( 44.0 m/s) at a wall, and the ball bounces back with little loss of kinetic energy. (a) what is the recoil speed of the earth ( 6 × 1024 kg)? m/svearth = m/s(b) calculate the recoil kinetic energy of the earth and compare to the kinetic energy of the baseball. the earth gets lots of momentum (twice the momentum of the baseball) but very little kinetic energy. kearth = j
kbaseball = j

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
