The rocket sled shown in the figure below accelerates at a rate of 50.0 m/s2. Its passenger has a mass of 69.0 kg.

(a)

Calculate the horizontal component of the force (in N) the seat exerts against his body. (Assume the +x-direction is to the right. Indicate the direction with the sign of your answer.)

N

Compare this with his weight by using a ratio.

|Fh|
|w|

=

(b)

Calculate the direction and magnitude of the total force the seat exerts against his body. (Enter the direction in degrees counterclockwise from the +x-axis and the force in N.)

For his engineering project, Fran¸cois built a model rocket of mass m = 0.55 kg simply by using materials he found lying around the lab and blueprints he found on the internet. The rocket’s propulsion is provided by a special battery-powered fan that is able to provide a constant force |Ffan| = 7.0 N – that is, once it is launched in a specific direction, the direction of the fan’s force does not change. The downside is that the rocket...

The diagram below shows a block of mass m=2.00kgm=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00NF1=4.00N, F2=6.00NF2=6.00N, and F3=8.00NF3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...
