Answer with Explanation:
We are given that


Differentiate x and y w.r.t t





Substitute t=1


Magnitude of velocity=

Hence, the magnitude of the missile's velocity=16.49 m/s


Substitute t=1



Hence, the magnitude of acceleration when t=1 s=
The wire needs to be sauderwired to be connected back into place to get energy into column so it came function properly again!
I think we will use the law of conservation of linear momentum;
M1V1 = M2V2
M1 = 4 kg (mass of the water balloon launcher)
V1=?
M2= 0.5 kg ( mass of the balloon)
V2 = 3 m/s
Therefore; 4 V1 = 0.5 × 3
4V1= 1.5
V1= 1.5/4
= 0.375 m/s
