Question

A car accelerates uniformly from rest and acquires a speed of 36km/he in 10 sec. Find 1. Acceleration 2. Total distance travelled 3. Velocity at end of 6th second
4. Distance travelled in the second

Answer 1

Answer:

3600 Kmph = 10 mps.

1. a = 10/10 = 1 M per sec ^2

2. S = 1/2 . 1× 100 = 50 meters

3. V(6) = 0 + 1x6 = 6 meters per sec.

4. s ( 2nd) = s(2)-s(1)= 1/2.1.( 4-1) = 3/2=1.5 meters
