Answer:
137.8 m
Step-by-step explanation:
The following data were obtained from the question:
Height (h) = 22 m
Initial velocity (u) = 65 m/s
Horizontal distance (s) =.?
Next, we shall determine the time taken for the motorcycle to get to the ground. This can be obtained as follow:
Height (h) = 22 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =?
h = ½gt²
22 = ½ × 9.8 × t²
22 = 4.9 × t²
Divide both side by 4.9
t² = 22/4.9
Take the square root of both side.
t = √(22/4.9)
t = 2.12 s
Finally, we shall determine the horizontal distance travelled by the motorcycle. This is illustrated below:
Initial velocity (u) = 65 m/s
Time (t) = 2.12 s
Horizontal distance (s) =.?
s = ut
s = 65 × 2.12
s = 137.8 m
Thus, the motorcycle will land at 137.8 m away from the cliff
