a. quadruple
b. double
c. 1/2 as big the previous force

Throw a single die and let the random variable X be the number on the die. construct the probability distribution including possible value of X and find the mean of the distribution.
A box is initially at rest on a smooth incline. If an external force is applied upward, the box will be
a. sliding upward
b. sliding up and down the incline
c. stationary
d. sliding downward
1.) Two forces act on a 55-kg box on a smooth level path. One force has magnitude 50 N directed 45 degrees clockwise from the positive x-axis, and the other has a magnitude 50 N at 45 degrees counter-clockwise from the positive x-axis. What is the net force that causes the box in motion?
a. 0
b. 50 N along positive x-axis
c. 100 N to the right
d. 70 N east

a. zero
b. greater than the actual weight
c. actual weight
d. less than the actual weight
3.) A roller-coaster car has a mass of 500 kg when fully loaded with passengers. At the bottom of a circular dip of a radius 40m, the car has a speed of 16 m/s. What is the magnitude of the force of the track on the car at the bottom of the dip?
a. 4.9 kN
b. 3.2 kN
c. 1.7 kN
d. 8.1 kN
You are given an array of N non-negative integers: A1, A2, ..., AN. An alternating subsequence is a subsequence in which the indices of any two consecutive elements differ by exactly two in the original array. That is, if Ai1, Ai2, ..., Aik is some subsequence, then for it to be an alternating subsequence, (i2 - i1 = 2), (i3 - i2 = 2), and so on should all hold true. Among all alternating subsequences, find the one which has maximum sum of elements, and output that sum.
Given an integer n (between 1 and 104) find two prime numbers (possibly same) p1,p2 such that p1+p2=n
In case there are multiple solutions, you can output any of them.
If there is no solution, then print -1 -1 instead.
