### (Solved) 2) An object is launched at a velocity of 8.50 m/s in a direction making an angle of 42° upward with the horizontal. Note: remember to use DEG when using your calculator

2) An object is launched at a velocity of 8.50 m/s in a direction making an angle of 42° upward with the horizontal. Note: remember to use DEG when using your calculator.

a) Draw a scheme that shows the motion of the object. Label the point at which the object starts moving as Xo = 0 m, yo = 0 m and to = 0 s, where xo, Yo is the initial position and to is the initial time. (submission work-up, 0.5 marks)

b) List all the known and unknown parameters (submission work-up, 0.5 marks)

c) What is the maximum height reached by the object? (1 mark)

An object is launched at a velocity of 8.50 m/s in a direction making an angle of 42° upward with the horizontal. Note: remember to use DEG when using your calculator. What is the total flight time (between launch and touching the ground) of the object? ( 2 marks)
