- A person on the top of a roof of a building (100 m) drops a ball. After 2s passed, a person who stands at the base of the same building throws a separate ball in the upward direction with a speed of 20 m/s. Assumes the two balls are traveling on the same vertical path. Will the two balls collide with each other? If so, what are their velocities as they collide with each other?arrow_forwardA balloonist, riding in the basket of a hot air balloon that is rising vertically with a constant velocity of 22.0 m/s, releases a sandbag when the balloon is 30.0 m above the ground.

- A skydiver leaps out of an airplane but accidentally forgets their parachute. They fall for 6.80 s before reaching terminal velocity and fall for the rest of the way to the ground at that constant terminal velocity. The total trip from the plane to the ground takes 96.6 s. Luckily, the skydiver lands in a tree and survives. How high above the tree was the airplane when the skydiver leaped out?arrow_forwardA piano has been pushed to the top of the ramp at the back of a moving van. The workers think it is safe, but as they walk away, it begins to roll down the ramp. If the back of the truck is 1.0 m above the ground and the ramp is inclined at 20°, how much time do the workers have to get to the piano before it reaches the bottom of the ramp?arrow_forwardYou toss a basketball up into the air vertically with an initial velocity of 16 m/s. If you release the ball from a height of 1.7 m above the ground, how high above the ground does it rise before falling back downwards?arrow_forward

What is the magnitude of the velocity (in m/s) when the packaged is released? Report your answer in the appropriate number of significant digits. Answer valuearrow_forwardConsider a grey squirrel falling from a tree to the ground. Use a coordinate system in which positive is downward for this problem. a) Find the squirrel’s velocity, in meters per second, just before hitting the ground when it falls from a height of 1.3 m. Ignore air resistance. b) The squirrel softens its landing by bending its legs when it touches the ground, thereby stopping itself over a distance of 7.6 cm. Assuming a constant rate of deceleration, find the squirrel’s acceleration during this process, in meters per second squared.arrow_forward
