A ball is thrown from the ground into the air. At a height of 9.1 m, the velocity is observed to be v = 7.1i + 6.8j in meters per second (x axis horizontal, y axis vertical and up).
(a) To what maximum height will the ball rise?
m
(b) What will be the total horizontal distance traveled by the ball?
(c) What is the magnitude of the ball's velocity the instant before it hits the gound?
m/s
(d) What is the direction of the ball's velocity the instant before it hits the ground?
°
A spacecraft is traveling with a velocity of v0x = 5675 m/salong the +x direction. Two engines are turned on for a time of 847 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 1.25 m/s2,while the other gives it an acc..
