The position of a particle is given by r = 3.0t ˆi − 2.0t 2 ˆj + 4.0 kˆ m where t is in seconds and the coefficients have the proper units for r to be in metres. (a) Find the v and a of the particle? (b) What is the magnitude and direction of velocity of the particle at t = 2.0 s ?
v=4m/sFrom the velocity-time graph, the velocity of the particle at t=1. 0s. 0 s is v=4m/s.
The position of a particle at time t is given by the relation x(t)= (v0α)(1−c−at) where v0 and α are constants .
The position of a particle moving along a straight line at any time t is given by s(t) = t2 + 4t + 4. The acceleration of the particle when t = 4 is 2 m/s2.
1 Answer. The answer is: x=−3 . The law that gives the position of the particle at the time t is given by the integral: x(t)=∫(4−6t2)dt=4t−6t33+c=4t−2t3+c .

−3.4cm/s .At t=4.0s t = 4.0 s , its velocity is −3.4cm/s . Determine the object's velocities at t=1.0s t = 1.0 s and t=6.0s t = 6.0 s . A particle moves along the x-axis according to the equation x(t)=2.0−4.0t2 x ( t ) = 2.0 − 4.0 t 2 m.
The acceleration of a particle is a constant. At t = 0 the velocity of the particle is (10^i+20^j)m/s. ( 10 i ^ + 20 j ^ ) m/s . At t = 4 s the velocity is 10^jm/s.
When t=2, the velocity of the particle is 4+2×2=8 m/s. After t seconds, the velocity of the particle is 4+2t m/s.
The position of a particle is given by r=3.0t^i−2.0t2^j+4.0^k m where t is in seconds and the coefficients have the proper units for r to be in metres.
We also note that the particle's position at t = 2 is given by . Thus the particle is moving away from the origin....Frozen in Time.tf(t).00000100000010.0000004999996082410 more rows
