Hi please help me ! :)

2) Ryan rides his skateboard at a constant velocity for a distance of 40 m to the north for 9.8 5. He then travels at a constant velocity for a distance of 60 m to the south for 15.15. Calculate his average: a) Speed for the trip. (3 marks) b) Velocity for the trip. (3 marks) 3) A bullet is accelerated from rest through a 1.00 m long rie barrel. The bullet has a muzzle velocity of 600 m/s. Determine the magnitude of the bullet's acceleration while it travels through the barrel. (5 marks) 4) Add the vectors 12 m [20 W of S] and 10 m [120]. You may wish to first draw a rough sketch of each vector, as well as their sum. (6 marks) 5) A cannon is set at an angle of 45 above the horizontal. A cannonball leaves the muzzle with a speed of 2.2 x 102 m/s. Air resistance is negligible. Determine the cannonball's: a) time of flight (2 marks) b) maximum height (2 marks)c) horizontal range (2 marks) 5) A motorboat heads due east at 10 m/s across a river that ows due south at 8.0 m/s. Determine the: a) velocity of the boat relative to the shore I (2 marks) b) Time it takes the motorboat to reach the other side if the river is 62 m wide (2 marks) c) Distance the boat travels downstream (2 marks) Use the following information to answer the question. 60 50 40 Velocity 30 (m/s) 20 10 0 0 2.0 4.0 6.0 8.0 10 Time (s) The acceleration, using one significant digit, is m/s2
