Just need some help with the following questions which are probably very easy to you guys. Here are the 2 questions I need help with.(adsbygoogle = window.adsbygoogle || []).push({});

1). A boat sails 150m due south and 150m due east. This takes a total time of 45s. Calculate (i). the boat's average speed and (ii) the boats average velocity.

2). A car traveling at 10 ms -1 due north speeds up uniformly to a velocity of 25 ms-1 in 5 s. Calculate the acceleration of the car during these 5 seconds. Let the direction of the motion of the car, due north, be taken as the positive (+) direction.

Thanks in advance.

Billy. Can email me at: annaporcel@talk21.com
