In a park: a 75 kg bicyclist rides 5.8 m/s north; a 24 kg dog runs 3 m/s east chasing a 3.3 kg squirrel running 2.6 m/s the same way; 200 kg park bench remains stationary; and a 43 kg child runs 1 m/s 45◦ south of east. What is the magnitude of the total momenta of this park system?
Report the value in kg*m/s rounded to the nearest whole number.

A 62-kg bicyclist rides his 10.3-kg bicycle with a speed of 13.5
m/s. Assuming contant acceleration, (a) How much work must be done
by the brakes to bring the bike and rider to a stop? kJ (b) How far
does the bicycle travel if it takes 4.7 s to come to rest? m (c)

A bicyclist rides on a North-South trail from her home to work.
She starts at home and rides due North for 22 minutes with a
velocity of 7.2 m/s. She gets tired, so she slows down and rides
for 36 minutes due North with a velocity of 5.1 m/s. Suddenly, she
realizes that she missed her destination, frantically turns around,
and rides due South for 8.0 minutes with a velocity of 10.1 m/s
before reaching work.
a. What is her...

A 2.9 kg block with a speed of 3.6 m/s collides with a 5.8 kg
block that has a speed of 2.4 m/s in the same direction. After the
collision, the 5.8 kg block is observed to be traveling in the
original direction with a speed of 3.0 m/s. (a) What is the
velocity of the 2.9 kg block immediately after the collision? (b)

A child m = 30 kg runs at vi = 5 m/s tangentially to a small
playground merry-go-round, aiming at the edge with idea of jumping
on and spinning around. The merry-go-round has mass 80 kg, radius
1m, and can be modeled as a thin solid disk.
1. What is the angular speed of the merry-go-round after the
child jumps on?
2. After the merry-go-round turns through 270◦ , the child jumps
off the merry-go-round radially and tumbles away at...

A car with mass 1309 kg is travelling north at a speed of 28.9
m/s. It collides at right angles with a truck (m=2733 kg)
travelling east at 16.6 m/s and the two vehicles stick together
after the collision. How much kinetic energy is lost during the
collision?
