Answer:
I am pretty sure you meant 1 hour so the answer is
2
Step-by-step explanation:
Since we want one hour we can multiply 1/4 by 4 to get 1 since we multiplied 1.4 by 4 we need to multiply 1/2 by 4, so we get 2
The tangent of the angle would be given by 14/18, so the angle would be:
tan⁻¹(14/18)
= 37.9 to the nearest tenth of a degree
Answer:
2.88m/s
Step-by-step explanation:
By using the law of conservation of momentum
Initial momentum = final momentum
v = is their combined velocity afterwards
Solving equation (1) for v
V = 2.88 m/s
Therefore the velocity afterward is 2.88 m/s.
