The average speed of the particle during the 5 second time interval isis 25m/s. Option C.
Calculation:-
Let acceleration = a
vi = 0
v1 = 50m /s
f = 5sec
v_{1} = v_{i} + at
a = 10 m/s^2
d = 1/2 a t ^ 2 +vi f
d = 1/2 * 10 *s ^ 2
d = 125m
Vavg = d/t = 125/5 .
Vavg = 25 m/s.
Acceleration is the rate of change of velocity over time, both in terms of velocity and direction. A point or object moving in a straight line accelerates as it accelerates or decelerates. Circumferential motion is accelerated because it always changes direction even at constant velocity.
Acceleration is the change in velocity over time. Whenever a change in velocity or acceleration in the direction of movement occurs. At constant velocity, acceleration is zero. Deceleration is called negative acceleration or deceleration.
