Question

car starts from rest with uniform acceleration of 2 centimetre per second square the distance covered by it in 10 seconds is

Answer 1

Answer:

100 cm

Explanation:

S=ut+½at^2

u=0 (starting from rest)

a=2

t= 10

Answer 2

GivEn:

• Time taken by car = 10 s
• Acceleration = 2 cm/s² = 0.02 m/s²

To find:

• Distance covered by car?

SoluTion:

Here,

Car starts form rest.

Therefore,

• Initial Velocity of car, u = 0 m/s

★ Using 1st equation of motion,

v = u + at

v = 0 + 0.02 × 10

v = 0.2 m/s

∴ Final Velocity of car is, v = 0.2 m/s

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

★ Now, Using 2nd equation of motion,

s = ut + ½at²

s = 0 × 10 + ½ × 0.02 × (10)²

s = 0 + ½ × 0.02 × 100

s = ½ × 2

s = 1 m

∴ Hence, Distance travelled by car in 10 sec is 1 m.
