A baseball is thrown at an angle of 23◦ relative
to the ground at a speed of 22.3 m/s. The ball
is caught 36.4649 m from the thrower.
The acceleration due to gravity is
9.81 m/s2 .
How long is it in the air?

To model a spacecraft, a toy rocket engine is securely
fastened to a large puck, which can glide with negligible
friction over a horizontal surface, taken as the xy plane.
The 4.00-kg puck has a velocity of 300
i m/s at one instant.
Eight seconds later, its velocity is to be (800
i $ 10.0
Assuming the rocket engine exerts a constant horizontal
force, ﬁnd (a) the components of the force and (b) its
