A toy rocket is launched at an initial velocity of 50 m/s at an angle of 75° with the horizontal. Write parametric equations to represent the path of the rocket.

Question

(A)x = 50t cos 75°y = 50t sin 75° – 4.9t2

(B)x = 50t cos 75°y = 50t sin 75° – 16t2

Answer 1

y = Yo + Vi t - (1/2)gt^2
g = 9.8 so (1/2) g = 4.9
so the last term has to be
-4,9 t^2
