Basic kinematics problems: Speed, collision, displacement, velocity, degrees

? Tom is chasing Jerry across a table 1.5 m high, Jerry steps out of the way at the last second, and tom slides off the edge of the table at a speed of 5 m/s. where will tom strike the floor and what velocity components will he have just before he hits the ground.

? Two objects are initially the same height above the ground. Simultaneously, one is released from rest and the other is shot off horizontally with an initial speed of 2.5 m/s. The two objects collide after falling 20.0 m. How far apart were the objects initially?

? A boat moves at 10 m/s relative to the water regardless of which direction it travels through the water. If the water in a river is flowing at 1.5 m/s, how long does it take the boat to make a round trip consisting of a 300-m displacement downstream followed by a 300-m displacement upstream?

? A river flows due east at 1.5 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 10.0 m/s due north relative to the water.
a) What is the velocity of the boat relative to shore?
b) If the river is 300 m wide, how far downstream has the boat moved by the time it reaches the north shore?

An ant walks 25.0cm eastward then 20 cm northward and then 14 cm westward.
What is magnitude and ants displacement in cm?

Data collected from the door of a physics classroom to another in building is 2m west, 14 m south, 25 east, 11 north, 2 m west. Find the direction of resultant displacement that is closest to _____degrees
(use counter clockwise from east convention)

Same as other problem but 2m west, 14 m south, 30 m east, 9 m north, 3 m west. The magnitude of the resultant displacement from the physics classroom to the assigned location is closest to ___meters

A Boy scout name d Dexter goes for a hike; he walked 9 km north 3 km east 11 km north and 15 km west. Find resultant displacement for Dexter's hike
