1. The graph in the figure shows the position of an object as a function of time. The letters H-L represent particular moments of time. At which moments shown (H, I, etc.) is the speed of the object (a) the greatest? (b) the smallest? oi- Time 2. A car accelerates from 10m/s to 30 m/'s at a rate of 3 m/s. How far does the car travel while accelerating? Answer: x = 133 m 3. A ball is thrown directly...

A ball is thrown vertically upward. Neglecting air resistance, which one of the following statements is FALSE. Select one: a. The kinetic energy of the ball decreases while the ball is going up. b. The sum of the kinetic energy and gravitational potential energy of the ball is constant. C. The kinetic energy of the ball increases when the ball is coming down. d. The gravitational potential energy decreases as the ball is going up
----------> (I must show all work)A tennis ball is thrown upward at an angle from point A. It follows a parabolic trajectory and hits the ground at point D. At the instant shown, the ball is at pointB. Point C represents the highest position of the ball above the ground.While in flight, how do the x and y components of the velocity vector of the ball compare at the points A and D?A) The velocity components are non-zero at A...
how i solve this problem A ball is thrown upward with a velocity of 20.0 m/s (a) how high it will go (b) time it takes to reach the highest point
A ball is thrown straight upward. Which of the following statements are correct about the ball's velocity (v) and acceleration (a) at the highest point in its path? O both v 0 and a 0 #0, but 0 There is not enough information to determine the velocity (V) and acceleration (a). ys0, but a 9.8 m/s2
Ba Example 2-16 Ball thrown upward A woman throws a ball upward into the air with an initial velocity of 15.0 m/s. Calculate: (a) How high it goes (b) The time for the ball to reach its maximum height Ignore air resistance. 2-7 Freely Falling Objects Example 2-16 Ball thrown upward A woman throws a ball upward into the air with an initial velocity of 15.0 m/s. Calculate: (c) How long the ball is in the air before she catches...
A ball is thrown straight upward in the air at a speed of 15.0 m/s. Ignore air resistance. a) What is the maximum height the ball will reach? b) What is the speed of the ball when it reaches 5.00 m?c) How long will the ball take to reach 5.00 m above its initial position on the way up? d) How long will the ball take to reach 5,00 m above its initial position on its way down?
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...
