A 40.0 kg child is standing on a 42 kg raft that is drifting with a velocity 0f 1.2 m/s [N] relative to the water. The child walks on the raft with a net velocity of 0.71 m/s [E] relative to the water. Fluid friction between the raft and the water is negligible. Determine the resulting velocity of the raft relative to the water. i and j vectors are not permitted. dont forget the angle

Water falls at the rate of 241 g/s from a height of 70.0m into a 718g bucket on a scale (without splashing). If the bucket is originally empty, what does the scale read 2.64s after the first drop of water reaches the bucket? | Submit Answer Incompatible units.

It's a snowy day and you're pulling a friend along a level road on a sled. You've both been taking physics, so she asks what you think the coefficient Part A of friction between the sled and the snow is. You've been walking at a steady 1.5 m/s, and the rope pulls up on the sled at a 28 ° angle. You estimate that the mass of the sled, with your friend on it, is 58 kg and that you're pulling with a force of 72 N. What answer will you give? Submit Request Answer

Find the terminal velocity of a spherical bacterium (diameter 2.00 µm ) falling in water. You will first need to note that the drag force is equal to the weight at terminal velocity. Take the density of the bacterium to be 1.10 × 10³ kg/m³ .

Figure 1 В А Three blocks, labeled A, B, and C, are connected by essentially massless strings that run over essentially massless and frictionless pulleys (as shown in Figure A above). Block A hangs straight down. The string from block A connects to block B which is sliding up and to the left along an inclined plane. The plane is inclined at an angle of theta = 0 = 52 degrees away from vertical. The coefficient of kinetic friction between block B and the plane is 0.38. Block B is connected by a different string to block C which hangs straight down. Block A has a mass of 4.1 kg. Block B has a mass of 3.7 kg. Block C has a mass of 2.5 kg. Block A is moving down and block C is moving up (the strings do not stretch). The only significant forces acting on the blocks are friction acting on block B, normal forces, tension forces, and gravity (with g = 9.81 m/s²). Calculate the %3D acceleration (in units of meters per second squared) of block A. For block A, a downward acceleration is…

Consider the three boxes m₂=8.83 kg, m=10.6 kg and m=4.72 kg which are connected by massless cords passing over frictionless pulleys. The box mrests on a frictionless tabletop while box m and box mare suspended at the ends of the cords connected to box m₁. What is the magnitude of acceleration and direction of motion of box m when the system is released from rest? mb ma mc 1.67 meters per second squared, downward 2.74 meters per second squared, upward 2.74 meters per second squared, downward 1.67 meters per second squared, upward
