Find the force of weight for a car sitting on an inclined plane of 35 degrees with a mass of 9kg.

9 N
100

Draw at least 3 vectors which yield a net force of 0 N.

The vectors should start and end at the same point when lined up head to tail.

Two balls are launched at different angles. The red ball is launched with a velocity of 80m/s and the blue ball is launched with a velocity of 80m/s. The red ball is launched at 10 degrees and the blue ball is launched at 90 degrees. Which ball has the greater time of flight?

Blue ball

Find the force of weight for a 20kg person standing on a hill 9 degrees above horizontal. 

20 N

If 2 cords are holding on a heavy object in mid-air and cord 1 is longer than cord 2, which cord has the greatest force of tension.

Cord 2

A car goes off a ramp. What will the velocity be at its peak? 

Just the horizontal velocity

Two students run down the hallway without socks. If student 1 exerts a greater force on the ground, does student 1 or student 2 run faster.

Student 1

An inclined plane is 7 degrees above the horizontal. Is the normal force the same or different for the same object if the inclined plane is 21 degrees.

Different

How do I find horizontal acceleration?

Find velocity and then F=ma.
