Answer:
C
Explanation:
horizintal speed stays same
only vertical speed changes
so H speed will stay 30 m/s
The velocity, 50 m/s, has two components - vertical and horizontal velocities.
The vertical component = 50 sin 30 = 25 m/s
The horizontal component = 50 cos 30 = 43.3 m/s
(a) Let t be the time taken for the vertical component to reach its peak from initial velocity = 25 m/s to its final velocity = 0.
Using the linear motion equation v = u - gt
0 = 25 - 10t
t = 2.5 s
Time taken to go up and down = 5 s
Time to hit the ground = 5 s
(b) Horizontal distance dealt x = 43.3 * 5 = 216.5 m
This is not the correct answer, but explains the problem thoroughly.
Velocity of plane is given as
towards north
towards south east
we can write the two velocity in vector form
now the net velocity will be given as
so the resultant velocity will be given as
and the angle of velocity will be
Answer:
frictonal force due to the surface of irregularities
