A bullet is fired horizontally from a rifle. Ignore air resistance. In which direction {horizontal or vertical) is the velocity greatest right after firing? A person wants to go to a destination that is 10 km away N and 10 km E. On the way there they take a stepwise approach where they go 1km N, then 1km E and repeat the process until they get to the destination. They walk with a speed of 5 km/hr. On the way back they go in a straight line with a speed of 3 km/hr and return to their starting point. What is the average velocity of the person during the trip? If a block of mass m=87 kg is sitting motionless on a table and has no other forces {besides gravity) being applied. The coefficient of static friction is u=0.26. What is the frictional force acting on the block? The same block as question above now has a horizontal force of 100 N acting to the right. What is the magnitude and direction of the frictional force
