5 days ago · Answer. The reaction force on the body can be found using the formula 𝑅 = 𝑚 𝑔 𝜃, c o s which gives 𝑅 = 0. 7 ( 9. 8) ( 6 6). c o s ∘. To two decimal places, the reaction force is 2.79 N. The resultant force on a body on an inclined plane, ⃑ 𝐹, is the sum of ⃑ 𝑅 and 𝑊. We can express this as 𝐹 = 𝑅 + 𝑚 𝑔.
4 days ago · A ball thrown from position A against a smooth circular wall rebounds and hits position B at the other end of the diameter through A. If the coefficient of restitution between wall and ball is $ e $ and $ \\theta = {30^ \\circ } $ , then find $ 3e $ .
4 days ago · In other words, if \(1\) red ball is placed on one side of a scale, in order to balance the scale, \(2\) blue balls must be placed on the other end. Balancing puzzles can be modeled as linear systems of equations since it is possible to derive linear relationships about elements on the scale (as mentioned above).

So many actors feel uncomfortable with the idea of marketing, branding and all other things to do with business. It feels like the business of acting and the craft of acting are on opposite ends of the ...
4 days ago · A ball of mass 5.0kg hits a smooth vertical wall normally with a speed of 2ms-1 and rebounds with the same speed. Determine the impulse experienced by the ball - SchoolNGR.
2 days ago · Step one of this body language acting exercise is the same as the last one: put your phone in airplane mode. But this time, sit yourself down in a public space and simply watch the world around you. Pretend the very moment you are experiencing is a scene in a movie and the people around you are the characters.
2 days ago · The angle θ in Eq.(2) (and (3)) is the angle of the final velocity vector of ball 2 with the x-axis. This will be determined separately later from the geometry of the collision (alternatively, one can also treat θ as a free parameter). Solving now Eq.(1) for vx,1' and Eq.(2) for vy,1' yields
