what is the model of projectile motion as the combination of independent horizontal and vertical motion?

An arrow has an initial velocity of 32 m/s, 30° to the horizontal. a) Find the time it takes for the arrow to reach the ground if it is shot from an original height of 22 m. (G.R.A.S.S.) b) What is the horizontal displacement of the arrow in this amount of time? (G.R.A.S.S)

A projectile is launched with an initial velocity of 28.6 m/s at 67.5 degrees with respect to the horizontal. What is the speed of the projectile 1.54 s after being launched. Assume the speed is measured in m/s.

PW-3 An elevator motor is capable of lifting a 2,500kg elevator 50.0m with a constant speed in 12.0 seconds. a) Apply Fet ma to find the force needed to lift the elevator. b) Find the power of the elevator motor in watts and in horsepower. (1H.P.-750W) c) If the power of the elevator motor is 200H.P., find the constant speed at which the 2,500kg elevator can be raised. d) If the power of the elevator motor is 200H.P., find the constant speed at which the elevator can be raised if the elevator and its contents have a mass of 4,000kg

After a constant acceleration of 2.31 m/s/s at 5.9 degrees above the +x-axis is applied by the motors of a boat for 9.3 seconds, the boat is moving at 38.55 m/s at 13.5 degrees above the +x-axis. What was the initial velocity of the boat? What is the initial angle from the positive x-axis?

K Solve for the indicated variable. Assume all variables are positive. QV₁ QV₂ T. L T₂ ; for T₁ (Simplify your answer.)

During a kick ball game, a ball is kicked with a velocity of 25m/s at an angle of 45 degrees above the horizontal. How long us the ball in the air and how far does the ball travel?

A ball is launched straight up and then falls straight back down to the ground. Which of the following statements is true about the ball at the peak of it's trajectory?   Question 3 options:   The magnitude of the ball's displacement relative to the ground is zero   The magnitude of the ball's velocity relative to the ground is zero   The magnitude of the ball's acceleration relative to the ground is zero   All of the above   None of the above

Refer to the information in Ball Throw to answer this question. The magnitude of the initial velocity of the ball when it is thrown into the air at 60.0° is 28.6 m/s  24.7 m/s 16.5 m/s 14.3 m/s

A projectile launched at 45° upwards from the ground takes 2.4 seconds to return to the ground. Approximately what speed was the projectile launched?
