Question

a car starting from rest acquires a velocity 50 m/s in 10 second. what is the acceleration​

Answer 1

Given :-

• Initial velocity = 0 [ beacuse it is starting from rest ]

• Final velocity = 50 m/s

• Time taken = 10 sec

To Find :-

• Acceleration

Solution :-

We have,

• u = 0
• v = 50 m/s
• t = 10 sec

Substituting the value in 1st equation of motion :-

➩ v = u + at

➩ 50 = 0 + a × 10

➩ 50 = 10a

➩ a = 50/10

➩ a = 5

Acceleration = 5 m/s²

Answer 2

v = 0

u = 50

t = 10

V = u + at

0 = 50 + a(10)

= 50 + 10a

10a = -50

a = -50/10

a = -5

Hence acceleration is -5
