Question

The diagram above represents a toy car starting from rest and uniformly accelerating across the floor. The time and distance travelled from the start are shown in the diagram. What was the acceleration of the cart during the first 0.4 seconds?

Answer 1

Give me the diagram for this Question

Answer 2

the acceleration of the car of the car during the first 0.4 second is

Explanation: as we know the second equation of motion

that is - S=ut + 1/2at square

so as it is given in the question that the cars starts from rest which means that

U=0 so the whole term UT =0

so by applying the formula

s=1/2at square we will get the answer

so as given in the question

s=96cm when t is

t=0.4sec

so by solving and putting the values in the equation we get

a = 12m/s square
