Question

predictions for projectile motion. They set up a system so that a beanbag is launched
horizontally off one of their desks with an initial speed of 4.2 m/s. They measure the
height of the desk to be 1.3 m.
a. What is the time of flight for the beanbag?
b. What is the range for the beanbag?

Answer 1

a)

Displacement equation in the vertical direction with 0 initial velocity yes?

h = 1.3 + 0t + (-9.8 / 2)t^2 metres, with t in s

= 0
