The initial speed of a body is 2.43 m/s. What is its speed after 3.07 s if it accelerates uniformly at 3.23 m/s2? Answer in units of m/s. What is its speed after 3.07 s if it accelerates uniformly at −3.23 m/s2? Answer in units of m/s.

A plane cruising at 232 m/s accelerates at 14 m/s2 for 4.7 s. What is its final velocity? Answer in units of m/s. How far will it have traveled in that time? Answer in units of m.

A ball is dropped from rest from a height of h. It takes 1 second for the ball to drop from h/2 to the ground. From what height was the ball dropped?

A pair of 328.1 N vectors are perpendicular. What is the magnitude of their resultant? Answer in units of N.

Consider the motion of a projectile. It is fired at t = 0. Its initial speed is 17 m/s and its initial projection angle is 35◦ from the horizontal. What is the maximum height of its tra- jectory? The acceleration due to gravity is 9.8 m/s2 . Answer in uni...

A book weighing 29 N is placed on a table. How much support force does a table exert on the book? Answer in units of N. (I know the answer to this part is 29 N) part 2: What is the net force on the book in this case? Answer in units of N
