1- a worker with spikes on his shoes pulls with a constant
horizontal force of magnitude 20 N on a box of mass 40 kg
resting on the flat, frictionless surface of a frozen lake. What
is the acceleration of the box ?
2- If we take east as x – axis and north as y - axis, then

2.5 km away with a speed of 5 km/hr. Finding the market
closed, he instantly turns and walks back home with a speed
of 7.5 km/hr. Find The average speed of the man over the
interval of time o to 40 min.

Calculate the moment of inertia along x & y axis and polar moment of inertia with respect to the centroidal axis using the figure shown below.
A vertical rectangular object of uniform mass M = 8 kg has sides a = 0,21 m and
b = 0,67 m. It is pivoted from point O as shown in the figure below. If a constant force of
F = 118 N along the diagonal is applied as shown below, determine the angular acceleration
of the rectangle in SI units at the instant shown. Express your answer using one decimal place.
Please use the convention: Clockwise (+), Counterclockwise (-) when expressing your answer.
Hint 1: The moment of inertia of a uniform disk about an axis of rotation passing through the
center of mass (CM) is ICM = M(a² + b²).
Hint 2: Don't forget the force of gravity!!! Take g = 9.80 m/s².
