A cannon barrel is 1.2 m long. A cannonball (20 kg) is fired horizontally off ofa 10 m tall cliff. The cannonball hits the ground at a range of 200 m. a) Find the velocity of the cannonball when it leaves the cannon. (A: 140£– ) b) Find the constant acceleration that was applied to the cannonball. (A: 8167£ ) c) How much constant force was applied to the cannonball while it was in the barrel of the cannon? (A: 163,333£ N)

A jet aircraft with a mass of 4,375 kg has an engine that exerts a force (thrust) equal to 59,900 N. (a) What is the jet's acceleration when it takes off? (Give the magnitude.) m/s? (b)What is the jet's speed after it accelerates for 7 s? (Assume it starts from rest.) m/s (c) How far does the jet travel during the 7 s?

Pls answer asap. Thank you Note: Computation must be complete and answer in 2 decimal places.

Two forces are applied to a 4.0 kg cart on a rough surface as shown. At a certain instant, force A is 32 N to the right, and force B is 20 N to the left. The friction force is 2.0 N. What is the acceleration of the cart at this instant, in m/s?? (Hint: What is the direction of the friction in this case? Draw a free-body diagram.) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
