An skier is moving at a speed of 4.00 m/s when she hits a downhill. If the hill accelerates her at a constant rate of 0.40 m/s2 and it takes her 5.00 s to get
down the hill, how long is the hill?*
a. 25 m
b. 21 m
c. 120 m
d. 50 m

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

Aforce of 8,480 n is applied to a chart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?

How long will it take a car traveling of a constant speed of 45m/s to cover the distance of a 2.5km?
