Answer:
(a). The velocity of bus at 2.0 sec is 6.8 m/s.
(b). The position of bus at 2.0 s is 11.8 m.
(c). , and x-t graphs
Explanation:
Given that,
Time t = 1.0 s
Velocity = 5.0
The Acceleration equation is
We need to calculate the velocity
Using formula of acceleration
On integrating
Put the value into the formula
Put the value into the formula
We need to calculate the velocity at 2.0 sec
Put the value of initial velocity in the equation
(b). If the bus’s position at time t = 1.0 s is 6.0 m,
We need to calculate the position
Using formula of velocity
On integrating
The position at t = 2.0 s
Hence, (a). The velocity of bus at 2.0 sec is 6.8 m/s.
(b). The position of bus at 2.0 s is 11.8 m.
(c). , and x-t graphs
