- the rocket starts from rest at t=0 and travel straight up. it's height above the ground as a function of time can be approximated by s=bt^2+ct^3, where b and c are constants. at t=10s, the rocket's velocity and acceleration are v= 229m/s and a=28.2 m/s^2 A.) determine the time in seconds at which the rocket reaches supersonic speed (325 m/s) B.) determine the value of constant B C.) determine the value of constant Carrow_forwardAn object's position as a func of time is given by ; x(t) = - 200 (( t + 1 ) ^ - 1) + 6t^2.

- The acceleration of a particle is a constant. At t=0 the velocity of the particle is (14.91 + 18.4ĵ) m/s. At t = 4.6 s the velocity is 11.4j m/s. (Use the following as necessary: t. Do not include units in your answers.) (a) What is the particle's acceleration (in m/s²)? = î+ 18.4 v(t) = (b) How do the position (in m) and velocity (in m/s) vary with time?

How much time did it take the particle to travel from point 1 to point 3?arrow_forwardThe displacement of a particle is given by s = 2t³ - 42t² + 120t - 68 where s is in feet and t is in seconds. Plot the displacement, velocity, and acceleration as functions of time for the first 16 seconds of motion. After you have made the plots, answer the questions. Questions: At t = 3.3 sec, S= i ft, v = i ft/sec, a = i ft/sec At t = 8.9 sec, S = ft, v = i ft/sec, a = i ft/sec Att = 14.2 sec, S= i ft, v = i ft/sec, a = i ft/sec The velocity is zero when t = i i sec and when t = i secarrow_forward

You have already stopped and measured the distance between adjacent poles as 40.0 m. You are now driving again and have activated your smartphone stopwatch. You start the stopwatch at t 5 0 as you pass pole #1. At pole #2, the stopwatch reads 10.0 s. At pole #3, the stopwatch reads 25.0 s. Your friend tells you that he was pressing the brake and slowing down the car uni- formly during the entire time interval from pole #1 to pole #3. (a) What was the acceleration of the car between poles #1 and #3? (b) What was the velocity of the car at pole #1?

The person's average speed is 67.0 km/h. (a) How much time is spent on the trip? 1.03 Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. h (b) How far does the person travel? 67.23 Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. kmarrow_forward

State this as a positive number and assume it has proper SI Units.arrow_forwardA runner is moving with a speed of 2.68[m/s]. How long will it take the runner to complete a 5.0[km] race? Express your answer in seconds. Ignore the time it takes to reach this speed, and assume the runner is always at this speed.arrow_forwardYour answer is partially correct. An object falls a distance h from rest. If it travels 0.550h in the last 1.00 s, find (a) the time and (b) the height of its fall. (a) Number i 3.414 Units (b) Number i 58.140 Units marrow_forward
