(Figure 1) In this problem, you will determine the resultant (net) force by combining the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive). How far (in meters) will the block move in 5.0 s? Recall that it starts from rest.
- help please. If a 1467 kg car, moving at 9 m/s north, hits and sticks to a 2237 kg truck, moving at 10 m/s south, and they travel off together at the same speed, find that speed. Hint: here the masses are moving in opposite directions, so the velocities should have opposite signs. Call North positive and South negative. Use the "hit and stick" or inelastic formula Also, a positive answer would indicate motion to the north and a negative answer would show southward motion - leave positive/negative in your answer.Mechanic Physics: Please make sure this is right!! In the figure, block A (mass 1.6 kg) slides into block B (mass 2.9 kg), along a frictionless surface. The directions of velocities before and after the collision are indicated; the corresponding speeds are vAi = 5.7 m/s, vBi = 2.7 m/s, and vBf = 4.4 m/s. What is velocity vAf (including sign, where positive denotes motion to the right)?he FBD of the block should have looked like this. 1. A contestant in a winter sporting event pushes a block of ice of mass m across a frozen lake as shown in the figure. The coefficient of static friction between the block and ice is μs, and the coefficient of kinetic friction is μk. θ is the angle the force makes with the x-axis. In this part, we are going to set-up Newton's second Law equations for the cases(1) when the ice block just starts moving, and(2) when it is accelerating to the right with an acceleration a. All answers are symbolic. ALL ANSWERS ARE CASE-SENSITIVE. Subpart 1: Newton's Second Law along the y-axis (i) Write Newton's Second Law along the y-axis by adding all forces in the y-direction taking into account their signs (forces pointing upwards are positive and downward are negative) in terms of the normal force N, weight mg, F and θ. In both scenarios, there is no acceleration along the y-direction, therefore, ay=0.…
