A golf ball is released from rest from the top of a very tall building. Choose a coordinate system whose origin is at the starting point of the ball, and whose y axis points vertically upward.
The acceleration of gravity is 9.8 m/s2 .
Neglecting air resistance, calculate the ve- locity of the ball after 2.17 s.
Answer in units of m/s.
What is the position of the ball after 2.17 s? (Neglect air resistance.)
Answer in units of m.
A cat chases a mouse across a 1.3 m high table. The mouse steps out of the way, and the cat slides off the table and strikes the floor 1.8 m from the edge of the table.
The acceleration of gravity is 9.81 m/s2 .
What was the cat’s speed when it slid off the table?
Answer in units of m/s.
The fastest recorded pitch in Major League Baseball was thrown by Nolan Ryan in 1974. If this pitch were thrown horizontally, the ball would fall 0.809 m (2.65 ft) by the time it reached home plate, 18.3 m (60 ft) away.
The acceleration of gravity is 9.81 m/s2 . How fast was Ryan’s pitch? Answer in units of m/s.
A cargo plane is flying horizontally at an altitude of 11.1 km with a constant speed of 561 km/hr when a large crate slides out of the rear of the plane. How long does it take the crate to hit the ground? The acceleration of gravity is 9.81 m/s2 .
Answer in units of s.
What is the horizontal distance of the crate from the point it fell off to the point where it hits the ground?
Answer in units of km.
