A spacecraft lands on a newly discovered planet orbiting the star 51 Pegasi. To measure the acceleration from gravity on the planet, an astronaut drops a rock from a height of 2 m. A precision timer indicates that it takes the rock 0.71 s to fall to the surface. What is the acceleration from gravity on this planet?
. A rock is dropped off the side of a bridge and hits the water below 2 s later. (a) What was the rock's velocity when it hit the water? (b) What was the rock's average velocity as it fell? (c) What is the height of the bridge above the water?
A hard rubber ball, not affected by air resistance in its motion. is tossed upward from shoulder height, falls to the sidewalk, rebounds to a smaller maximum height, and is caught on its way down again. This motion is represented in Figure OQ2.17, where the successive positions of the ball through are not equally spaced in lime. At point the center of the ball is at its lowest point in the motion. The motion of the ball is along a straight, vertical line, but the diagram shows successive positions offset to the right to avoid overlapping. Choose the positive y direction to be upward. (a) Rank the situations through according to the speed of the ball |Yl at each point, with the largest speed first, (b) Rank the same situations according to the acceleration a% of the ball at each point. (In both rankings, remember that zero is greater than a negative value. If two values are equal, show that they are equal in your ranking.)
Jayce threw his softball high in the air as Yukari looked down from her-storey home to see how high he threw it. Jayce threw his ball high enough to reach the floor of the second storey. If jayce threw the ball at an initial velocity of 30 m/s, and an initial height of 1.22 m, with one storey equivalent to at least 3.05 meters. 1. How fast is the ball after 0.2 seconds? 2. With the initial values, how high the ball fly after 3 seconds?
The car moves on a very long straight highway at an initial velocity of 2.0m/s when it started to accelerate at a rate of 1.5m/s2. When the car reaches a diplacement of 1km, it started to decelerate at constant rate until it stop. A. What is the car's final velocity (assumed that the car directs in a constant direction) before it started to decelerate (slow down)?*Please explain also*
Chris stands on top of a giant rock outcrop, 250 feet above the ground.Chris throws a grapefruit upwards, into the air, with initial velocity of 50 feet per second. The grapefruit has a trajectory such that it will fall all the way to the ground. Use calculus to write the equation of the displacement (position) of the grapefruit as a function of time using initial position s = 250 and ground level as position s = 0. Use acceleration a = -32 feet per second per second
John throws a ball vertically upwards with an initial velocity of 26.2 m/s. Determine:(i) The height to which the ball will rise above its initial height.(ii) The time taken to reach this peak height.(iii) The total time from when it leaves John’s hand until it hits the ground.
A stone is thrown downward with a speed of 19 m/s from a height of 17 m. (acceleration due to gravity: 10 m/s2)How long does it take (in seconds) for the stone to hit the ground?
Spaceman Spiff is stranded on an alien planet. In order to repair his spaceship, he needs to know what the acceleration due to gravity is on the planet. Spiff stands ona a cliff, throws a rock horizontally, and measures the time it takes to hit the ground 20m below. His data is shown in the following table. Calculate the acceleration due to gravity on this planet. Plot the velocity as a function of time. Can you show all the calculations please?
A car accelerates at 4 m/s2 for 3 seconds. The direction of its acceleration is due west. If its initial velocity was 45 m/s, due east, and its initial position is zero, what is its final position? Round your answer to the nearest meter. Choose positive direction east.
A derrick boat approaches a two mile marker 100m ahead at a velocity of 28.5 m/s . The pilot reduces the throttle, slowing the boat with a constant acceleration of -3.40 m/s^2. How long i seconds does it take the boat to reach the marker? What is the velocity in m/s of the boat when it reaches the marker? Indicate the direction with the sign of your answer.
