- At some airports there are speed ramps to help passengers get from one place to another. A speed ramp is moving converyor belt on which you csan iether stand or walk. Suppose a speed ramp has a length of 117 m and is moving at a speed of 2.1 m/s relative to the ground. In addition, suppose you can cover this distance in 73 s when walking on the ground. If you walk at the same rate with respect to the speed ramp that you walk on the ground, how long does it take for you to travel the 117 m using the speed ramp?arrow_forwardIn 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.) Compare your answer with thr free-fall acceleration, 9.80 m/s^2arrow_forwardAn object has a position function x(t) = 5t m. (a) What is the velocity as a function of time?

Standing [x] cm from the table it jumps, leaving the ground at an angle of [th] degrees, landing on the edge of the table. What is the initial speed of the mouse in meters per second?arrow_forwardif a person can jump a maximum horizontal distance ( by using a 45 degrees projection angle) of 3.66 m on earth, what would be his maximum range on the moon, where the free-fall acceleration is g/6 and g = 9.80 m m/s^2?

- On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into theSnohomish River below. The swimmers stepped off the bridge,and I estimated that they hit the water 1.5 s later. (a) How high wasthe bridge? (b) How fast were the swimmers moving when theyhit the water? (c) What would the swimmers’ drop time be if thebridge were twice as high?arrow_forwardA particle moves along a straight line with a velocity in millimeters per second given by v = 400 – 16t where t is in seconds. Calculate the net displacement As and total distance sT traveled during the first 8 seconds of motion.arrow_forwardThe velocity of a particle moving along a straight line is given by v = 25t²- 80t -200 where v is measured in meters per second and t in seconds. It is given that the object is located 100 m to the left of the origin at t = 0s. Compute velocity when acceleration is zero position(s) the object changes direction.arrow_forward
- An object’s position function, s, in meters, is given by s(t)= -4.9t 2 +13.2t, where t is measured in seconds. b) Determine the velocity of the object just at the instance it hits the ground (not after), rounded to the nearest tenth. Note the velocity is not zero!arrow_forwardThe cannon on a battleship can fire a shell a maximum distance of 28.0 km. (a) Calculate the initial velocity of the shell. m/s(b) What maximum height does it reach? (At its highest, the shell is above a substantial part of the atmosphere--but air resistance is not really negligible as assumed to make this problem easier.) m(c) The ocean is not flat, since the earth is curved. How many meters lower will its surface be 28.0 km from the ship along a horizontal line parallel to the surface at the ship? Does your answer imply that error introduced by the assumption of a flat earth in projectile motion is significant here? (Select all that apply.) The error is significant compared to the distance of travel. The error is insignificant compared to the size of a target. The error could be significant compared to the size of a target. The error is insignificant compared to the distance of travel.arrow_forwardA vehicle accelerates down an on ramp and eventually reaches highway speed.
