Thank you!

a = 0 so Fnet = m(0) = 0 so the answer is a (500 N to the east), because Ff will be equal to the 500 N west

Fnet = ma but the question doesn't give me mass or acceleration

Homework Statement A boat moves across the water at a constant 30 mph towards the west. If the motor is generating a thrust of 500 M then the force of friction on the boat must be... a. 500 N to the east b. 500 N to the west c. less than 500 N to the east d. less than 500 N to the west...

What would happen if you were shot with a cannon ball in space? How badly do you reckon it would hurt, compared to if you were shot with the same cannon ball on Earth?

Wouldn't that be Δy, which I tried using in attempts 2 and 3?

Homework Statement What angles should an arrow be launched if it leaves the bow @ speed of 60 m/s and is trying to hit a target that is 150 m away? Assume target is same height as bow. Suppose the arrow is fired at an angle of 30 degrees & misses the target & hits the ground 1.8 m below from...

I am currently taking calculus, and we have used differential equations. However, I believe either Algebra 2/Trig or Precalc is required for the course. I am choosing to do test corrections, and the "why" part is mandatory.

An object has initial speed u and acceleration a. After traveling a distance s, its final speed is v. Which of the following includes the two conditions necessary for the equation, v^2 = u^2 +2as, to apply? I know the answer is a has constant magnitude and a has constant direction, but I am...
