Question

a particle is projected in x-y plane under the influence of gravity with velocity (3i^+4j^) m/s find the following:
i) time of flight(T)
ii) maximum height(H)
iii) horizontal range(R)​

Answer 1

Answer:

horizontal range (R) is the answer

Answer 2

Answer:

time of flight= 2usin©\g

u=3i^+4j^

g=9.8

©=45

t=2×12×0.7071/9.8

t=1.731
