Answer:
T= 327.04 N
Explanation:
Initial velocity , u = 0 m/s
Final velocity ,v= 15.4 m/s
m = 584 kg
t= 27.5 s
We know that
v= u + a t
15.4= 0 + 27.5 a
a= 0.56 m/s²
From second law of Newtons
T= m a
T= 584 x 0.56 N
T= 327.04 N
The position of the particle when it changes direction is x = 3.0 m
Explanation:
The position of the particle is given by the equation
In order to determine its position when it changes direction, we need to find the time t at which the velocity of the particle becomes zero.
The velocity of the particle si given by the derivative of the position, therefore:
The velocity is zero when:
And therefore, the position at t = 0.41 s is

Answer:
7.61 m/s backwards
Explanation:
Initial momentum = final momentum
0 = (880 kg) v + (12.4 kg) (540 m/s)
v = -7.61 m/s
The cannon's recoil is 7.61 m/s backwards.
