Answer:
Explanation:
The cannonball goes a horizontal  distance of 275 m . It travels a vertical distance of 100 m 
Time taken to cover vertical distance =  t , 
Initial velocity u = 0 
distance s = 100 m 
acceleration a = 9.8 m /s² 
s = ut + 1/2 g t²
100 = .5 x 9.8 x t²
t = 4.51 s 
During this time it travels horizontally also uniformly so 
horizontal velocity Vx = horizontal displacement / time 
= 275 / 4.51 = 60.97 m /s 
Vertical velocity Vy 
Vy = u + gt 
= 0 + 9.8 x 4.51 
= 44.2 m /s 
Resultant velocity 
V = √ ( 44.2² + 60.97² )
= √ ( 1953.64 + 3717.34 )
= 75.3 m /s 
Angle with horizontal Ф
TanФ = Vy / Vx 
= 44.2 / 60.97 
= .725
Ф = 36⁰ .

Answer:(a)0,(b)1.061 kg-m/s
Explanation:
Given
mass of ball is 0.10 kg
Initial speed is 15 m/s
Maximum height reached by ball is h

final velocity =0


thus momentum of ball at maximum height is 0 as velocity is zero
For halfway to maximum height

where 


v=10.61 m/s
Thus its momentum is
