FIGURE 4.4 shows three objects A, B and C are kept in static equilibrium. The mass of B is 2.0 kg. Object A is just about to slide on the table. The coefficient of static friction between A and the horizontal table is 0.30. Calculate the
(a) mass of C = 2.83 kg
(b) mass of A = 6.67 kg

Help me out please, i want to cry.. the answer is already given. But i want to know the working

What mass will a pumpkin have a force of 450 newton’s accelerates it to 110 m/s^2? include the correct units.

What is the major limitation to the light microscope?

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
