You are standing very close to a building that is 15 m high and you throw a ball upwards from the ground with an initial velocity of 15 m/s. Your friend is on the roof of that building, and throws a second ball downwards with an initial velocity Vo.F; your friend throws the ball O.25 second after you threw yours. Calculate the velocity Vo,F of your friend's ball if the two balls collided at the height of 10 m above the ground. Take g=10m/s².

A 50g superball traveling at 25m=s bounces o a brick wall and rebounds at 22m=s. A high-speed camerarecords this event. If the ball is in contact with the wall for 3:5ms, what is the magnitude of the averageacceleration of the ball during this time interval? (Note: 1ms = 1 x 10^-3 s)
A baseball player uses a very massive golden bat to hit a rubber ball off of a tee. If the bat is moving 20 m/s when it hits the ball, what will be the speed of the ball as it leaves the bat? (Hint: What change of ball velocity would a flea see while riding on the bat, thinking it to be stationary?) Give your answer in m/s but do not write the units.
A student who aspires to ace his quiz in Phys134 went to a wishing well. He dropped his first 10-peso coin and made a quick wish. Two seconds after he dropped his first coin, he threw another 10-peso coin vertically downward with a speed of 30m/s. How long will it take the second coin to overtake the first?
Milton wants to throw a bag of candy and love notes into the open window of his girlfriend’s bedroom 10.0 m above the ground. Assuming it just reaches the window and he throws the love gifts at 60.0o to the ground, at what velocity should he throw the bag? Could you show me the steps necessary to solve this problem? Thank you!
I was standing on the side of a 10-m foot bridge, holding a ball while watching a car approaching the bridge at uniform speed. When the car was 15 meters away from where I was standing, the ball that I was holding slipped in my hand and the car arrived at the bridge when the ball hit the ground. What was the speed of the train? ( Assume that the final velocity of the ball is NOT zero)
Sam is standing on a balcony while holding two objects. She reaches over the railing and drops object A from a height of 20.0 m above the ground. 0.3 seconds later, she throws object B directly upward with a speed of 4.00 m/s. One second after she dropped object A, the velocities of the objects are measured. At that time, find: D. Object A's velocity relative to Object B
An airplane flies with a velocity of 55.0 m/s [ 35o N of W] with respect to the air (this is known as air speed). If the velocity of the airplane according to an observer on the ground is 40.0 m/s [53o N of W], what was the wind velocity? please do not solve in terms of "i" and "j" .
You are standing very close to a building that is 15 m high and you throw a ball upwards from the ground with an initial velocity of 15 m/s. Your friend is on the roof of that building, and throws a second ball downwards with an initial velocity Vo.fi your friend throws the ball 0.25 second after you threw yours. Calculate the velocity VoF of your friend's ball if the two balls collided at the height of 10 m above the ground
A ball is thrown downward with an initial velocity of 12 m/s. Using the approximate value of g = 10 m/s2, calculate the velocity of the ball 1.6 seconds after it is released. The velocity of the ball is ____ m/s.
You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 139m/s. How much time does it take for the impulse, which travels at a distance of 1.81m, to reach your brain?
A sandal is dropped from the top of a 17-m-high mast on a ship moving at 1.75 m/s due south. Take the deck of the ship to be y=0 m. Set up a table of knowns for the motion of the sandal relative to the ship. If the quantity is currently unknown, simply enter "unknown". Note that these variables are measured with respect to a coordinate system moving with the ship. a=? m/s^2 Calculate the velocity of the sandal relative to the ship when it hits the deck. Check the sign of the velocity. v=? m/s Calculate the velocity of the sandal relative to a stationary observer on the shore when it hits the deck in terms of unit vector notation. Check your signs. Hint: Relative to a stationary observer on the shore, the vertical motion of the sandal is the same as that measured by an observer on the ship. In addition, the sandal will have a horizontal velocity. What is the horizontal velocity equal to? v= ? m/s i+ ? m/s j
Two balls collide in mid-air. Both have mass .2 kg. Ball A has a velocity of (--20 i + 3j) m/s before the collision, and (15 i + 12j) m/s after the collision. If ball B was initially moving with velocity (40i + 6j) m/s, find its velocity just after the collision. Your answer must be a vector.
