A brother pulls his sister in a wagon for a time t using a force Fpull at an angle θ above the +x-axis. The sister/wagon have a combined mass m, initial velocity v0, and experience a frictional force Ff. t = 2 minutes | Fpull | = 250N m = 85 kg v⃗0= 1.2 m/s (x⃗) F⃗f= -180N (x⃗)

a)Find the angle θ for Fpullthat would give the wagon a final velocity of 2.3 m/s (x⃗)after the pull time t.

b)How far has the wagon traveled in this time?

c)Find the angle θ for Fpullthat would cause the wagon to stop after the pull time t.

d)How far has the wagon traveled in this time?

You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15 m. What...

A quarterback is set up to throw the football to a receiver who is running with a constant velocity ~vr directly away from the quarterback and is now a distance D away from the quarterback. The quarterback estimates that the ball must be thrown at an angle θ to the horizontal and the receiver must catch the ball a time interval tc after it is thrown. Assume the ball is thrown and caught at the same height y = 0...

Sir Lost-a-Lot dons his armor and sets out from the castle on his trusty steed (see figure below). Usually, the drawbridge is lowered to a horizontal position so that the end of the bridge rests on the stone ledge. Unfortunately, Lost-a-Lot's squire didn't lower the drawbridge far enough and stopped it at θ = 20.0° above the horizontal. The knight and his horse stop when their combined center of mass is d = 1.10 m from the end of the...
