Question

UESTION 2 A projectile is fired at an angle 8-53P with respect to the horizontal. It has an initial speed we150m/s. Assume that the ground is level. a) Determine the x and y components of the projectile's initial velocity b) Calculate the time of flight, t. Calculate the total distance R(often called the range) traveled in the x direction; in other words, find where the projectile lands d) Find direction of the projectile's motion sik seconds after the firing. or down? Give two reasons to justify your answer e) Six seconds after the firing is the projectile moving up

Explanation / Answer

1.

Ux= 150 cos 53= 90.27 m/s

Uy= 150 sin 53= 119.8 m/s

======

b)

Time of flight

T= 2*u sin x/g= 2*119.8/9.8= 24.448 second

=====

c) range= u cos x *T= 90.27*24.448= 2207 m

======

d)

Vy= 119.8- 9.8*6= 61 m/s

Vx= 90.27 m/s

Angle, = arctan ( 61/90.27)= 34 with horizontal

=====

e) it still moving upward

=====

Commemt in case any doubt.. good luck
