Two objects are allowed to fall from the same height to the ground. They both start from rest at the same time. One is just released and falls straight downward. The other is placed on a frictionless inclined plane that makes an angle of θ with the horizontal. Which one hits the ground with the highest speed? Ignore air resistance.
Group of answer choices
You need the angle of the incline to determine the answer.
The object that falls straight downward.
The object on the inclined plane.
You need the masses to determine the answer.

Two identical objects start at the same height above level ground. Simultaneously, object A is dropped and object B is launched horizontally with a speed of 20 m/s. Assume that air resistance is negligible. a) Which object hits the ground first, or do they hit the ground at the same time? b) Which object hits the ground with the greatest speed, or do they hit the ground with the same speed? c) If the two objects started at a height...
1. An object undergoes projectile motion. The objects launch height and landing height are the same. It travels horizontally 1.20 km in 4.00 seconds. Find the launch angle if the initial speed of the object is 350 m/s. 2. A 12.5 kg blue cart is released from rest at the top of a 2.25 m incline. It travels down a frictionless track to the bottom of the incline and then continues on a horizontal frictionless track where it collides with...

Two identical objects are dropped from rest at the same time. Object A is dropped from twice the height of object B. If there is no air resistance, which statement is true? None of the answers given is true. Both objects hit the ground at the same time. Object A takes twice the time to fall as object B. Object A takes four times the time to fall as object B.
Two uniform spheres of identical mass and radius are placed on
inclined planes at the same height h and inclination angle θ. One
plane is rough and causes one sphere to roll down the plane; the
other is frictionless, and so the sphere on it slides down the
incline.
Find the ratio of the kinetic energies of the two spheres at the
bottom of the incline: .

Two objects are connected by a light string passing over a light, frictionless pulley. The object of mass 5.0 kg is released from rest. Using the isolated system model, (a) Determine the speed of the 3.0 kg object at the moment just before the 5.0 kg object hits the ground.
