Question

(a) A ball is fired with velocity of 30m/s and an angle of 45 degree with the x-axis. Find the position vector of the ball after 1 sec?( cos 30 = sin 30 = 0.7). (b) Two blocks (m=2kg) and (M=3kg) are in contact on a horizontal rough surface. A horizontal force(F=10N) acts on M and moves both blocks. If the coefficient of friction between the blocks and the surface is (0.1) , Draw a free-body diagram for m and M and find: (1) The acceleration of the system (2) The force that M acts on m

Answer 1

Answer:

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
