The brakes are applied to a moving van, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.30 s to a final velocity of 1.75 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? (b) What was its acceleration (in m/s2) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction with the sign of your answer.)

A car is travelling at a constant speed of 100 km.hr at the highway when the driver noticed that the bridge 10 m away is cut off. If the driver immediately applied the brakes upon noticing the cut off bridge, what must be his deceleration so he would not fall to the river?
A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 12 m/s, skates by with the puck. After 3.0s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 4.0 m/s, how long does it take him to catch his opponent?
A typical jetliner lands at a speed of 160 mi/h and decelerates at the rate of (10.0 mi/h)/s. If the plane travels at a constant speed of 160 mi/h for 1.00 s after landing before applying the brakes, what is the total displacement of the aircraft between touchdown on the runway and coming to rest?
A car driving on a straight track accelerates at a rate of 3.2 m/s^2 for 4 secs. If the initial velocity of the car was 5.1 m/s, and initial position was 0 m, what's the final velocity?
During a hard sneeze, your eyes might shut for 0.38 s. If you are driving a car at 94 km/h during such a sneeze, how far does the car move during that time?
After jumping, a skydiver descends vertically towards the ground, with the parachute open, at a constant velocity of 4.9 m/s. When passing a height of 12.5 m, he drops a coin that was in his pocket. What is the time difference between the arrival of the coin and the parachutist on the ground? Disregard, in the coin's movement, the resistance of the air and use that the acceleration of gravity has a module of 10.00 m/s2. a. 4,70 s b. None of the other alternatives. c. 1,58 s d. 1,39 s e. They hit the ground at the same time. f. 2,55 s g. 1,17 s h. 0,97 s

During a walk on the Moon, an astronaut accidentally drops his camera over a cliff. It leaves his hands with zero speed, and after 2.00 s it attains a velocity of 8.30 m/s downward. How far has the camera fallen after 7.90 s?
A car is 126 m from a stop sign and traveling toward the sign at 29 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?
What is the initial velocity of a person who has an acceleration of 15 m/s^2 and reaches a max velocity of 6 m/s after .5 seconds at this constant acceleration?
A UCI student is running at her top speed of 5.1 m/s to catch a Shuttle bus, which is stopped at the bus stop. When the student is still a distance 42.0 m from the Shuttle bus, it starts to pull away, moving with a constant acceleration of 0.163 m/s2 .For how much time does the student have to run at 5.1 m/s before she overtakes the bus?
