A moderate wind accelerates a pebble over a horizontal xy plane with a constant acceleration a = (5.00 m/s^2)i + (7.00 m/s^2)j. At time t = 0, the velocity is (4.00 m/s)i. What are the (a) magnitude and (b) angle of its velocity when it has been displaced by 12.0 m. parallel to the x axis?

Please someone give me an answer: A uniform metre rule has a 4N weight hanging from one end. The rule balances when suspended from a point 0.1 from that end.

a) draw a diagram to show the rule and the forces on it.
b) calculate the weight of the rule

please show workings out and how to draw it. Thanks

if energy is equal to matter times the speed of light squared,doesnt that mean you have to get the matter to travel faster than the speed of light to get the results.how fast is the speed of light squared?can light go that fast?

You’ll see them hit the floor at about the same time.
But if you drop them off the top of a high ladder, you’ll see the golf ball hit first. What is your explanation?

Say you have a rope...on one end a force of 50 N is applied, on the other a force of 20 N. I know that this will cause acceleration in the direction of the 50 N force...but what is the tension in the rope??

Ok, here's the problem...

"If 50 grams of hot water at 80degrees celsius is poured into a cavity in a very large block of ice at 0 degrees celsius, what will be the final temperature of the water in the cavity? How much ice must melt in order to cool the hot water down to this temperature?"

How do I go about finding this answer? Am I supposed to use Q = mcDT?
