Question

A. Answer the following problems. Show your complete solution.

1. A car from rest accelerates at 2 m/s2 for 30 seconds. What is the distance

covered by the car?

2. A taxi from rest accelerates uniformly over a time 5 seconds and covers a

distance of 10 m. Determine the accelerations of the taxi?​

Answer 1

Answer:

I)Ans is 900m

• We know s= ut+½at²
• u=0
• ½ × 2× 900
• so , ans is 900

2)Ans is ⅘

• We know s= ut+½at²
• We know s= ut+½at²u=0
• 10=½×a×25
• 20=25a
• 20/25=a
• 4/5 =a

I hope this would be helpful

Answer 2

$\huge\bold{\mathtt{\red{A{\pink{N{\green{S{\blue{W{\purple{E{\orange{R}}}}}}}}}}}}}$

I)Ans is 900m

We know s= ut+½at²

u=0

½ × 2× 900

so , ans is 900

2)Ans is ⅘

We know s= ut+½at²

We know s= ut+½at²u=0

10=½×a×25

20=25a

20/25=a

4/5 =a
