5. (-/6 Points) DETAILS SERPSE 10 4.6.P.033 MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A farm truck moves due east with a constant velocity of 14.50 m/s on a limitless horizontal stretch of road. A boy riding on the back of the truck throws a can of soda upward (see figure) and catches the projectile at the same location on the truck bed, but 19.0 m farther down the road. (a) In the frame of reference of the truck, at what angle to the vertical does the boy throw the can? (b) What is the initial speed of the can relative to the truck? m/s (c) What is the shape of the can's trajectory as seen by the boy? a symmetric section of a parabola opening downward a straight line segment upward and then downward An observer on the ground watches the boy throw the can and catch it. (d) In this observer's frame of reference, describe the shape of the can's path. a symmetric section of a parabola opening downward a straight line segment upward and then downward (e) In this observer's frame of reference, determine the initial velocity of the can. magnitude m/s direction • above the horizontal Need Help?

Answer 1

(a) Here the boy catches Projectile at same location , SO in same frame of reference the Projectile does not move along X-axis. So it thrown upwards. .. OOP Wirito vertical (b) From, V-agt t5-12.15 19 1.31 s 14.50 ::V= (9.81) (1-31) = 6043 m/s

d since, he thrown up wards the trajectory were to him was Stoline d) For observer , it looks like parabolic motion a e) From, 1 Vol Vx2 +V42. I vol = V2.4.5)2 +(6•0332 Ivol = 15.86 m/s. O=tan-116.43 14.5 ( 24
