After solving a difficult physics problem, an excited student throws his book straight up. It leaves his hand at 3.9 m/s from 1.5 m above the ground. (a) How much time Moes it take until the book hits the floor? (b) What's its velocity then?
During practice a football player throws a football straight up into the air to see how high it will go. The initial velocity of the football was 7.6 m/s, and he released it .80 m from the ground. Find the maximum height the ball reached from the ground.
A student throws a small ball straight upward with an initial speed of 14.7 m/s a) What is the velocity of the ball 0.100 s before it reaches its highest point b) What is the velocity of the ball 0.100 s after it reaches its highest point
5. A football is kicked straight up into the air and hits the ground 4.7 seconds later. There is no air resistance. A. How long does it take to reach the highest point? B. What is its velocity at its highest point? C. How high does it rise? D. With what speed did the ball leave the foot? E. What is the speed of the ball just before it hits the ground?
A student standing on the ground throws a ball straight up. The ball leaves the student's hand with a speed of 14.0 m/swhen the hand is 2.50 m above the ground. How long is the ball in the air before it hits the ground? (The student moves her hand out of the way.) Express your answer with the appropriate units.
A softball pitcher throws a ball straight upward as hard as she can. According to your stopwatch, it takes exactly 4.20 seconds for the ball to (all back to the pitcher's hand Assuming no air drag: What was the speed at which the pitcher threw the ball upward? What is the maximum height reached by the ball? It taken 2.10 seconds to reach maximum height At half of that time. 1.05 seconds, how high is the ball? (Is it half-way...
Assume that a softball is thrown straight up with an initial velocity: v=vo experiences a drag force due to air resistance given by: Farag = - bv a. Use F = ma to show that the appropriate differential equation is given by: mat= -mg - kmy [where k = 1 b. Show by direct substitution that: v(t) = -9 + [kvote-kt sat isfies the differential equation. C. Assuming the ball is thrown straight up with velocity v = vo, find...
