21) using third equation of motion,
s = v^2/2a
= 4349.7^2 /(2*11.235)
= 8.42*10^5 m

A baseball is hit upward and travels along a parabolic arc before it strikes the ground. Which one of the following statements is necessarily true? The velocity of the ball is a maximum when the ball is at the highest point in the arc. The velocity of the ball is zero m/s when the ball is at the highest point in the arc. The x-component of the velocity of the ball is the same throughout the ball's fight. The acceleration...
Question 19 and 20 The package follows a cured path, but it is always vertically below the airplane. The package follows a straight line path that lags behind the airplane. A car travels due east at 12 m/s. It makes a turn due north and continues to travel at 16 m/s. What is the net velocity of the car? 20 m/s, 53 degree with the east 25 m/s, 37 degree with the east 28 m/s, 35 degree with the east...

B) neither the ball's velocity nor its acceleration is zero. C) the ball's acceleration is zero but not its velocity. D) theball'saccelerationpointsupwards. E) the ball's velocity points downwards.
1. A baseball is hit so that it travels straight upward after being struck by the bat. A fan observes that it takes 3.20 s for the ball to reach its maximum height. (a) Find the ball's initial velocity. (b) Find the height it reaches. 2. The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with acceleration of -5.40 m/s2 for 4.30 s, making straight skid marks 64.6...
----------> (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...
A rocket is fired from rest at x=0 and travels along a parabolic trajectory described by y^2=[170(10^3)x]m. a.) If the x component of acceleration is ax=((1/2)t^2)m/s^2, where t is in seconds, determine the magnitude of the rocket's velocity when t = 11 s. b.) Determine the magnitude of the rocket's acceleration when t = 11 s.
St.A balis thrown directy upward and experiences no air resistance. Which one of the following statements about its motion is correct? a. The velocity of the ball is downward while it is traveling up and upward while it is traveling down. b. The velocity of the ball is upward while it is traveling up and downward while it is traveling down but is zero at the highest point when the ball stops. c. The velocity of the ball is downward...
