Are Saying car has a uniform acceleration of 4 Metre square what distance will it cover in 10 second after start?

Text Solution

200 m500 m900 m400 m

Answer : A

Solution : Here, acceleration, `a = 4 ms^(-2)`, time taken, `t = 10 s` <br> initial velocity, `u = 0`, distance, `s = ?` <br> From `s = ut + (1)/(2)at^(2)`, `s = 0 xx 10 + (1)/(2) xx 4 (10)^(2) = 200 m`

Text Solution

Solution : Initial Velocity of the car, u = 0`ms^(-1)` <br> Acceleration, a = 4m `s^(-2)` <br> Time, t = 10 s <br> We know Distance, s = ut + (1/2) `at^(2)` <br> Therefore, Distance covered by car in 10 second = `0xx10+(1//2)xx4xx102` <br> = `0+(1//2)xx4xx10xx10m ` <br> = `(1//2) xx400m ` <br> = 200m
