Two people are pulling a boat through the water as in Figure P4.20. Each exerts a force of 600 N directed at a θ = 45.0° angle relative to the forward motion of the boat. If the boat moves with constant velocity, find the resistive force vector F exerted by the water on ...

Well the force in the direction of motion each pulls with it 600cos45 so the pulling force is 2*600*cos45. If the boat is not accelerating, the friction force should be equal to that.

A frictionless plane is 10.0 m long and inclined at 33.0°. A sled starts at the bottom with an initial speed of 4.30 m/s up the incline. When the sled reaches the point at which it momentarily stops, a second sled is released from the top of the incline with an initial speed ...

In Figure P4.30, m1 = 10.0 kg and m2 = 4.5 kg. The coefficient of static friction between m1 and the horizontal surface is 0.60 while the coefficient of kinetic friction is 0.30. Figure P4.30 (a) If the system is released from rest, what will its acceleration be? 1 m/s2 (b) If...
