Answer:
1331.84 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 0
s = Displacement = 490 km
a = Acceleration
g = Acceleration due to gravity = 1.81 m/s² = a
From equation of linear motion
The speed of the material must be 1331.84 m/s in order to reach the height of 490 km
Answer:
Explanation:
Given
Launch angle =u
Initial Speed is
Horizontal acceleration is
At maximum height velocity is zero therefore
Total time of flight
During this time horizontal range is
For maximum range
(b)If a =10% g
thus
