Meixiu and joey used what they have learned to solve the following problem. a projectile is launched with a launch angle of 65° with respect to the horizontal direction and with initial speed 72 m/s. how long does it remain in flight?

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
