Question

An ideal projectile of mass 0.890 kg is launched with an initial angle of 45.5 degrees with respect to the horizontal and an initial speed of 27.1 m/s. As the projectile reaches the top its trajectory, what is the magnitude of the acceleration it is experiencing?

Answer 1

The acceleration that the projectile experiences is, neglecting the influence of air resistance, always equal to g--9.8m/s^2.

Answer 2

The rigidity Fx , between the mass and earth at a distance x = -GMe m /x² Me = Earth mass , m= projectile mass artwork required to advance from R to 5R is [R , 5R] ? - Fx dx = GMe m[ a million/R - a million/5R] = 4/5 Gm Me / R = earnings in ok.E (artwork - potential Theorem , W= ?ok.E) = a million/2m V² V= ? (8/5GMe/R) , exchange the values This exhibits a mosquto or Elephant may well be raised with the comparable artwork carried out (autonomous of m)
