Answer:
1320
Explanation:
There are 60 seconds per minute so just multiply 22 by 60.
Assuming that the stone is thrown vertically... let's say it's a 1 kg stone.It doesn't matter if it's thrown upwards or downwards as (assuming no air friction) it will pass the original throwing point with the same downwards velocity as it had upwards, 3 seconds previously. So it starts with 1/2 m v^2 = 0.5 * 1 * 15^2 = 112.5 J of keThen k.e. gained = gpe lostk.e. gained = m g h = 1 * 10 * 50 = 500 J of Ke gainedso the final (total) ke is 612.5 J which = 1/2 m v^2 = 0.5 v^2 here
so 0.5 v^2 = 612.5so v^2 = 1225so v = 35 m/s
Speed is a scalar quantity (meaning it can be measured using a single number that represents the amount), while velocity is composed of the scalar quantity plus the direction. As the 100-meter sprint only takes place in one direction, the speed and velocity for this is just the same. For the 400-meter sprint however, the direction of your speed changes as you turn for her curved part of the race. Therefore, a direction change is happening.
Answer:The horizontal forces can be summed as vectors in order to determine the net force. Fnet = ∑Fx = 5.20 N, right - 3.29 N, left = 1.91 N, right.
