While running, the person is only moving in one dimension
Therefore, the velocity only has one component.
While jumping, the person is moving in two dimensions
Therefore, the velocity has two components.
VxFinding the total velocity
Δx= 2.2 m
Δy= -1.0m (bc the cat falls down)
What are we looking for??
The cliff is 200 m high
Vi = Vx
Vx,iProjectiles Launched at An Angle
Vx,iComponents of Initial Velocity for Projectiles Launched at an angle
42.0 mWhat do we know?
Find t using the horizontal eqn:
Δx=vxΔt = vicos(θ)t
Vx,iWhat is the initial vertical velocity of the ball?
Vx,iWhat is the total initial velocity of the ball?
