A car starting from rest requires a speed of 20 metre per second in covering a distance of 100 M calculate the acceleration of the car |
|
Answer» - Initial velocity of car is 0 m/s Final velocity of car is 20 m/s Distance covered by car is 100mTo Find :- Acceleration of car Solution :- ❍ We can find the acceleration by putting the values in the third EQUATION of motion :: v² = u² + 2as Where, V denotes final velocity u denotes initial velocity a denotes acceleration s denotes distance covered ⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀ Finding Acceleration :- => ( 20 )² = ( 0 )² + ( 2 × a × 100 ) => 400 = 0 + 200a => 200a = 400 - 0 => 200a = 400 => a = 400/200 => a = 2m/s² ⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀ Henceforth, acceleration of car is 2m/s² |
