A child attaches a toy car to a bunch of balloons. The child releases the toy car at ground level. Assume the toy car has a constant acceleration of 0.400 m/ s2 and air resistance is negligible. After 12.0 s the toy car detaches from the balloons.
(a) Calculate the height of the toy car at 12.0 s.
(b) Calculate the speed of the toy car at 12.0 s.
(c) How high does the toy car travel above ground level? (d) How
long is the toy car in the air?

An airplane releases a ball as it flies parallel to the ground at a height of ℎ=285 m as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height ℎ from the release point, calculate the speed ? of the plane. Neglect any effects due to air resistance, and use ?=9.81 m/s2 for the acceleration due to gravity.

A 3-kg toy car sits at the highest point of a 13-meter-high hill. The car begins to roll down the slope from rest. Assuming the car coasts freely, without any friction or air resistance, what is the car's speed at each of the indicated points? Use for the acceleration due to gravity, g - 9.80 m/s* Note: the diagram below is NOT to scale. Car's speed Car's speed Number Number m/s m/s 13 m r's speed Number 2 m 6...

A shotput thrower releases the shot with a release speed of 15m/s and a release angle of 42° above the horizontal. The initial height that the thrower releases the shot is 2 m. In all the problems, neglect the effect of air resistance. 1. What is the maximum height reached by the shot (relative to the ground)? 2. How long is the shot in the air for? 3. How far does the shot travel horizontally? 4. What is the vertical...

Tim attaches the string of a 0.10 kg yo-yo to his finger and releases the yo-yo from rest. As the yo-yo spins down, Tim keeps his finger motionless which allows the yo-yo to be treated the same as a freely rolling object. After the yo-yo drops a distance of 0.90 m, it has a translational speed of 4.0 m/s and an angular speed of 180 rad/s. What is the moment of inertia of the yo-yo? Air resistance and friction are...
