Answer:
Explanation:
Using the equation of motion v = u + at to get the speed at which the object would be travelling.
v is the final speed (in m/s)
u is the initial velocity (in m/s)
a is the acceleration (in m/s²)
t is the time taken (in secs)
Given parameters
u = 0m/s
t = 10s
a = g = 9.8m/s²
Substituting this values into the formula;
v = 0+9.8(10)
v = 0+ 98
v = 98m/s
<em>Hence the rock will be travelling at a speed of 98m/s.</em>

Hope this helps! <3
First thing plot a right angle with angle of elevation of 35degrees as shown in figure then use SOHCAHTOA.
Ay/Helicopter = sin 35
Ay = 86 sin 35 = 36.8237
Ax/Helicopter = cos 35
Ax = 86 cos 35 = 77.7175
Note: I ignore the negative signs coz they signify direction
