A car travels with a uniform velocity of 20ms for 5s the brakes are then applied and the car is uniformly retarded it comes to rest in futher 8 second. By drawing a graph between velocity and time find 1)distance traveled in 5 sec.

Answer:
A car that travels with a uniform velocity of 20ms for 5s the brakes are then applied and the car is uniformly retarded it comes to rest in further 8 second.
By drawing a graph between velocity the distance traveled in 5 sec is 100m
Explanation:
Velocity / speed is given by the following formula:
Speed/velocity = distance / time
Distance = velocity × time
Distance = 20m/s × 5s
= 100m
The distance travelled in the first
5 seconds is 100m
Using the velocity time graph. We calculate this distance as the area under the graph.
The shaded area under the graph will give the distance travelled.
The shaded area is a rectangle of 20 by 5 units
Area = 20 × 5 = 100
The distance travelled by the car in the first 5 seconds = 100m
