At time t = 0, a particle has a velocity of m a(t) v = 4.00. The following graph shows the particles S acceleration vs. time. What was the particle's velocity at t = 3.00s ? a. t time(s) 4 b. What was the particle's instantaned acceleration at t = 3.00s ? С. What was the average acceleration between t = 1.00s and t = 3.00s ? 2.

Solve it asap. My last attempt. Need 100% correct answer. Multiple votes will be done...

I need part d and e

A cyclist rides down a long straight road at a velocity (in m/min) given by v(t) = 400 - 20t, for 0≤t≤ 10. a. How far does the cyclist travel in the first 3 min? b. How far does the cyclist travel in the first 10 min? c. How far has the cyclist traveled when his velocity is 350 m/min?

Please help me ho can I sovle this question?

С. 13 m/s? D. 4.2m/s? 2. A car has an initial position of 2.7m, an initial velocity of -1.42 m/s, and a constant acceleration of 1.7m/s. What is the position of the car at the time of 1.65s? A. 1.96m В. 6.7m С. 3.8m D. 2.5m 3. Mr. Purley crashed his car with the greatest g force ever survived by a human being. He decelerated from 53.6m/s to zero in a distance of only about .59m calculate Mr. Purley's acceleration. B. 2874m D. 3234m A. 2687m C. 2435m 4. An astronaut drops a rock on an asteroid. The rock is released from a height of 1.45m above the ground 1.89 seconds later. What is the acceleration due to gravity on this asteroid. A. -.17 m/s2 C. -.70 m/s² B. .35 m/s² D. .406 m/s2 MacBook Air

The position of a particle moving a long x-axis is given by x (t) =8 t²- 2t3, where x in meter and t in .is in seconds. Find the acceleration at t = 3 .0 s :Select one .A -42.0 m/s? .B m/s? 6.0 .C m/s? 20.0- .D m/s? 6.0- .E m/s? 20.0

A rock is thrown vertically upward with a speed of 14.0 m/sfrom the roof of a building that is 70.0 m above the ground. Assume free fall. 1) In how many seconds after being thrown does the rock strike the ground? Express your answer in seconds.   2) What is the speed of the rock just before it strikes the ground? Express your answer in meters per second.

olem 1. A stone is dropped from the top of a building and falls freely from rest. What is its position (height) and its velocity after 1.0s, 2.0s, and 3.0s? To find for the position (height), we will use: Know that initial velocity (vi) = 0 a. Find h after 1.0s h=0(1.0s)-(9.8 m/s)(1.0s)2 2 |h=v₁t - 9² 2 h=0-9.8m 2 h=-4.9 m (negative sign denotes downward direction) b. Find h after 2.0s h=0(2.0s) - (9.8 m/s²)(2.0s)² 2 h=0-39.2 m 2 h = -19.6 m or 19.6 m downward Given: v₁ = 20 m/s Find: a. v after 1s b. v after 5s c. d after 1s d. t from origin to maximum height d from origin to maximum height e. Solutions: a. y after is use: V₁ = v₁ - gt vy=20 m/s-(9.8 m/s²)(1.0s) vy= 20 m/s -9.8 m/s vy=10.2 m/s b. v after 2s use: Sample Problem 2. A boy threw a ball upward with an initial velocity of 20 m/s and was able to catch it before it reached the ground on its return. a. What was the ball's velocity after 1s? b. What was the ball's velocity after 2s? c. What was its displacement after 1s? d. How…
