A particle is projected with an intial velocity of u ms^(−1) at an angle α to
the ground from a point O on the ground. Given that it clears
two walls of hieght h and distances 2h and 4h respectively from O.
(a) find the tangent of α
(b) the maximum hieght
(c) the range and period of the particle
(d) show that u^2 = (4/(26)) gh
please sir can you help me using the actual equations of projectile motion?
th position vector of a particle p of mass 3 kg is given by
r = [(cos 2t) i + (sin 2t)j] m
given that p was intitialy at rest.
find the cartesian equation of its path and describe it.
