Question

a racing car has a uniform acceleration of 4 ms-2 what distance will it covers in 10 s after start​

Answer 1

Answer:

Given :-

• A racing car has a uniform acceleration of 4 m/s².

To Find :-

• What is the distance will it covers in 10 seconds after it start.

Formula Used :-

$\clubsuit$ Second Equation Of Motion Formula :

$\bigstar \: \: \sf\boxed{\bold{\pink{s =\: ut + \dfrac{1}{2} at^2}}}\: \: \: \bigstar$

where,

• s = Distance Covered
• u = Initial Velocity
• t = Time Taken
• a = Acceleration

Solution :-

Given :

• Acceleration = 4 m/s²
• Initial Velocity = 0 m/s
• Time Taken = 10 seconds

According to the question by using the formula we get,

$\implies \bf s =\: ut + \dfrac{1}{2} at^2$

$\implies \sf s =\: (0)(10) + \dfrac{1}{2} \times (4)(10)^2$

$\implies \sf s =\: 0 \times 10 + \dfrac{1}{2} \times (4 \times 10 \times 10)$

$\implies \sf s =\: 0 + \dfrac{1}{2} \times 400$

$\implies \sf s =\: 0 + 200$

$\implies \sf\bold{\red{s =\: 200\: m}}$

$\therefore$ The distance travelled by the racing car is 200 m .
