Explanation :

It is given that :

Initial velocity, v_0=50\ m/s

Launching angle, \theta_0=36.9^0

The motion followed by this object is called as its projectile motion.

the horizontal component is given by:

x_t=x_0+v_0cos\theta_0t.......(1)

Put all values in equation (1)

For t = 0, x_t=0

For t = 1 s, x_1=0+50\ cos(36.9)\ 1=39.95\ m

For t = 2 s, x_2=0+50\ cos(36.9)\ 2=79.9\ m

For t = 3 s, x_3=0+50\ cos(36.9)\ 3=119.85\ m

For t = 4 s, x_3=0+50\ cos(36.9)\ 4=159.8\ m

For t = 5 s, x_4=0+50\ cos(36.9)\ 5=199.75\ m

For t = 6 s, x_3=0+50\ cos(36.9)\ 6=239.7\ m

Hence, this is the required solution.

Given:
v = 50.0 m/s, the launch velocity
θ = 36.9°, the launch angle above the horizontal

Assume g = 9.8 m/s² and ignore air resistance.
The vertical component of the launch velocity is
Vy = (50 m/s)*sin(50°) = 30.02 m/s

The time, t, to reach maximum height is given by
(30.02 m/s) - (9.8 m/s²)*(t s) = 0
t = 3.0634 s
The time fo flight is 2*t = 6.1268 s

The horizontal velocity is
u = (50 m/s)cos(36.9°) = 39.9842 m/s
The horizontal distance traveled at time t is given in the table below.

Answer:

  t, s    x, m
------  --------
     0   0
     1   39.98
     2   79.79
     3   112.68
     4   159.58
     5   199.47
     6   239.37
