The other day, while riding my bike, I was forced to stop quickly to avoid a squirrel in the middle of the road 60 feet ahead. I decelerated at a constant rate of 15 ft/sec², skidding all the way. One second into the slide, my trip computer said I was going 27 ft/sec. How far did I skid before stopping? Did I avoid hitting the squirrel? Round to the nearest tenth

3. A ball is thrown upwards at 13.0 m/s toward the ceiling located 6 m above the point where you release the ball. Air resistance is negligible. Objects falling near the earth's surface with no forces acting except gravity have a downwards acceleration of magnitude g. For this problem use g = 10 m/s². Write any equation you use in symbolic form before substituting in numbers. Make a labeled picture with symbols and all relevant values. Put a coordinate system on the a. picture by indicating the location of the origin and position direction. b. Find the time taken to reach the ceiling. Find the velocity just before the ball touches the ceiling. C.
Compute your Average velocity in the following two cases: (a) You walk 61.4 m at a speed of 2.47 m/s and then run 61.4 m at a speed of 3.34 m/s along a straight track. (B) You walk for 1 minute at a speed of 2.47 m/s and then run for 1.8 minutes at 3.34 m/s along a straight track
At an air show, a jet plane has velocity components vx =695km/h and vy =415km/h at time 4.35 s and vx =938km/h and vy =365km/h at time 7.52 s. Please answer A,B,C,D Thank you.
A penny is dropped from the observation deck of the Empire State building (215.0 m above ground). With what velocity would it strike the ground if air resistance were negligible? Assume the free-fall acceleration g = 9.80 m/s2. Ignore air resistance. If the velocity is downward, enter a negative value and if the velocity is upward, enter a positive value. answer in m/s
1b. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. What are the components of the initial velocity? v0x = ____m/s v0y = ____m/s
A missile silo is used to launch test rockets vertically upward out of the silo, giving the rocket an initial speed of 79.0 m/s at ground level. As the rocket clears the silo, the engines fire, and the rocket accelerates upward at 4.20 m/s2 until it reaches an altitude of 1,080 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2.(You will need to consider the motion while the engine is operating and the free-fall motion separately. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) (a) Determine the velocity of the rocket (in m/s) at the end of the engine burn time and also the burn time (in s). (For the velocity, indicate the direction with the sign of your answer.) velocity at end of engine burn timev= m/sengine burn timet= s (b) Determine the maximum altitude of the rocket (in m) and the total time (in s) for the rocket to reach this…

3. In Physics, the height of a free-falling object at a given time t is given by h = –16t² + v,t + h., where v, is the initial velocity, and h, is the initial height. A student throws a ball upward from a height of 48ft, initially at 32 ft/s. What is the maximum height of the ball?
