A 64 kg students stands on a very light, rigid board that rests on a
bathroom scale at each end, as shown in figured P8.1 What is the
reading on each of the scales? - ANSWERS-156.96 N
One end of a spring is attached to a wall. A 25 N pull on the other end
causes the spring to stretch by 3.0 . What is the spring constant? -
ANSWERS-833.3 N/m
How much force does it take to stretch a 10 m long, 1.0 cm diameter
steel cable by 5.0 mm? - ANSWERS-79 x 10^2 N
At what speed do a bicycle and its rider, with a combined mass of 100
kg, have the same momentum as a 1500 kg car traveling at 1.0 m/s? -
ANSWERS-15 m/s
, A small, 100 g cart is moving at 1.20 m/s on a frictionless track when
it collides with a larger, 1.00 kg cart at rest. After the collision, the
small cart recoils at 0.850 m/s. What is the speed of the large cart after
the collision? - ANSWERS-0.205 m/s
A little girl is going on the merry-go-round for the first time, and
wants her 47 kg mother to stand next to her on the ride, 2.6 m from
the merry-go-round's center. If her mother's speed is 4.2 m/s when the
ride is in motion, what is her angular momentum around the center of
the merry-go-round? - ANSWERS-213.87 kg x m^2 /s
A 2.0 kg book is lying on a 0.75 m high table, you pick it up and place
it on a bookshelf 2.3 m above the floor. During this process,
a) how much work foes gravity do on the book?
b) how much work foes your hand do on the book? - ANSWERS-a) -
30.38 J
b) 30.38 J
Which has the larger kinetic energy, a 10 g bullet fired at 500 m/s or a
10 kg bowling ball sliding at 10 m/s? - ANSWERS-the bullet has a
larger kinetic energy
Your friend's frisbee has become stuck at 16 m above the ground tree.
You want to dislodge the frisbee by throwing a rock at it. The frisbee
is stuck pretty tight, so you figure the rock needs to be traveling at
least 5.0 m/s when it hits the frisbee. If you release the rock 2.0 m
above the ground, with what minimum speed must you throw? -
ANSWERS-62.182 m/s
