A 2.0kg mass moves at a velocity of 1.0ms^-1 southward. What is the constant force which causes the mass to move at a velocity of 1.0m^-1 eastward 6.0s later?
a)0N
b)0.3N in the southeast direction
c)0.33N in the northwest direction
d)0.47N in the southwest direction
e)0.47N in the northeast direction
Homework Answers
Change in velocity
V = i - ( - j) = i + j
Acceleration
a = V/t
a = (i +j) / 6
Magnitude of acceleration
a = ( 1/6) sqrt ( 1 +1)
a = 0.236
Force is given by
F = ma = 2 * 0.236 = 0.47 N (North east direction)

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
