Question

5: An object of mass m is projected with initial velocity v0 at an angle of θ degrees

to the horizontal. discuss the motion(position, velocity, acceleration) of the object

throughout the period of the flight. With appropriate choice of values for param￾eters (m, v0 and θ), plot the velocity and acceleration as functions of time on the

same graph. Discuss these graphs. Assume that the surrounding air offers no resistance

Answer 1

$t=\frac{2v_0\sin \theta}g,$

$h=\frac{v_0^2\sin^2\theta}{2g},$

$l=\frac{v_0^2\sin2\theta}{g}.$
