2. A man who has a mass of 80 kg can run up a flight of stairs of 20 steps in 5 seconds. Given the each steps in 20cm high, how much power does the man use to run up the flights of stairs?
acceleration of a car that comes to a stop from a velocity of 60 m/s in a distance of 360 m
Find the acceleration of a car that comes to a stop from a velocity of 60 m/s in a distance of 360 m.
Four point charges (two with q=2.50µC and two with q=-3.0µC) are situated at the corners of a square of a side 1.0m. Find the resultant force that the charge at A will experience due to charges at the corners of the square and it’s direction.
(this question had a diagram but the diagram looks like a square, qA is in the top left corner, qB is in the top right corner. -qC is in the bottom corner of left and -qD is in the bottom corner of right.)
