A ball is thrown straight up. It passes a 2.00-m-highwindow 7.50 m off the ground on its path up and takes 0.312s to go past the window. What was the ball’s initial velocity?Hint: First consider only the distance along the window, andsolve for the ball's velocity at the bottom of the window. Next,consider only the distance from the ground to the bottom ofthe window, and solve for the initial velocity using the velocityat the bottom of the window as the final velocity.
In the 1991 World Track and Field Championships in Tokyo, Mike Powell jumped 8.95 m, breaking by a full 5 cm the 23-year long-jump record set by Bob Beamon. Assume that Powell’s speed on takeoff was 9.5 m/s (about equal to that of a sprinter) and that g 9.80 m/s2 in Tokyo. How much less was Powell’s range than the maximum possible range for a particle launched at the same speed?
In the 1968 Olympics in Mexico City, Bob Beamon shattered the record forthe long jump with a jump of 8.90 m. His speed on takeoff was 9.5 m/s.How close did this athlete come to the maximum possible range in theabsence of air resistance?
Particles A and B move to the right along a horizontal line. They start at a point O, s meters isthe directed distance of the particle from O at t seconds, and the equations of motion for particlesA and B are s = 4t2 + 5t and s = 7t2 + 3t, respectively. If t = 0 at the start, for what values of twill the velocity of particle A exceed the velocity of particle B?
(The complete question is in the picture) Consider the velocity-time graphof a particle moving in one dimension, as shown below.Assuming that the particle starts at the origin, which ofthe following statements is true?A. The particle returns to the origin atthe end of the trip.B. The particle is at rest at time t =2.0 to t = 4.0 seconds.C. The farthest distance reached bythe particle is 45 [m] from the origin.D. The position of the particle is thesame at t = 3.0 [s] and t = 7.0 [s]seconds.
A car moves at 95km/h past a police car that stops by the side of the road. One minute later, thepolice car chasesat0.9m/s2. How far the police car reachesthe car?
A car can be braked to a stop from the autobahn-likespeed of 200 km/h in 170 m. Assuming the acceleration is constant,find its magnitude in (a) SI units and (b) in terms of g. (c) How muchtime Tb is required for the braking? Your reaction time Tr is the timeyou require to perceive an emergency, move your foot to the brake,and begin the braking. If Tr = 400 ms, then (d) what is Tb in terms ofTr, and (e) is most of the full time required to stop spent in reactingor braking? Dark sunglasses delay the visual signals sent from theeyes to the visual cortex in the brain, increasing Tr. (f) In the extremecase in which Tr is increased by 100 ms, how much farther doesthe car travel during your reaction time?
You are driving along at a constatnt speed of 26 m/s and you look down at your phone to read a text message for 2.5 seconds. How many meters does the car travel while you are not looking?
Suppose that a world-class long jumper jumped on the moon with the same initial velocity as that which would produce a world record breaking distance of 10.5 m on earth. What would be the range of this lunar long jump? Gravitational acceleration on the moon is 1.67 m/s2.
Person A is waiting patiently at a traffic light when person B zooms past him at 25.5m/s. after 1.4s, person A's car accelerates at a rate of 4.5m/s^2 . Will person A be able to catch up to person B? If so how long? If not, how close will person A get to person B? What would the frusteration distance be? (how close would they get to eachother?)
Two motor vehicles, BMW and Ducati, are driving at SLEX southbound lane. At 9:00:00 am they are 100 meters apart and both having a velocity of 100 km/hr with BMW on the lead. The BMW suddenly decelerates at a constant rate of 5m/s while the Ducati retains its velocity. How many seconds after 9:00 am will the Ducati start to overtake the BMW? Express your answer in unit of second. How much distance has the BMW travelled from 9:00 am to the moment the Ducati starts to overtake? Express your answer in unit of meter. How much distance has the Ducati travelled from 9:00 am to the moment it starts to overtake the BMW? Express your answer in unit of meter. What is the distance between both motor vehicles after 20s? Express your answer in unit of meter.
