1. A student is walking at 1.22 m/s. If they weighs 552 N, what is the magnitude of their
momentum? Do not put units in answer Question 26 5 pts For which one of the following
situations will the path length equal the magnitude of the displacement? OA train travels 5 miles
east before it stops. It then travels 2 miles west OA ball rises and falls after being thrown straight
up from the earth's surface. OA ball on the end of a string is moving in a vertical circle 0 A toy
train is traveling around a circular track. O A ball is rolling down an inclined plane. Question 27
5 pts During the spin-dry cycle of a washing machine, the motor slows from 90 rad/s to 30 rad/s
while the turning the drum through an angle of 180 radians. What is the magnitude of the angular
acceleration of the motor? 20 rad/s 10 rad/s 32 rad/s 64 rad/s
Solution
weight W = m*g
mass m = W/g
momentum P = m*v
v = speed = 1.22 m/s
momentum P = W*v/g
P = 552*1.22/9.8
P = 68.7 m/s
================================
26)
the path and magnitude of diplacement are equal only when the object travels

2. straight with out any change in direction
A ball rolling down an inclined plane
=================================
27)
In constant angular
w^2 - wo^2 = 2*alpha*dtheta
30^2 - 90^2 = 2*alpha*180
angular acceleration alpha = -20 rad/s^2
magnitude = 20 rad/s^2 <<<-------------ANSWER
