A shotputter throws the shot with an initial speed of 15.0 m/s at a 37.0 ∘ angle to the horizontal. Calculate the horizontal distance traveled by the shot if it leaves the athlete's hand at a height of 2.10 m above the ground.
Here we have
vertical velocity of shortput = = 9.027 m/s
time taken to reach the ground ,using the kinematic equation we have
putting s= -2.10 m
u = 9.027 m/s
we have
4.9t2 - 9.027 t -2.10 = 0
solving the quadratic equation we have
t = 2.051 seconds
now
horizontal velocity =
horizontal distance covered = (horizontal velocity )(time of flight) = 11.98 2.051 = 24.57 m
the horizontal distance traveled by the shot = 24.57 m
