a racing car has a uniform acceleration of 8 m s? what distance will it cover in 10 second after start. About the author Alice
Answer: 400m Explanation: From Newton’s laws of motion, s = ut + 1/2 at² Here u = 0 s = 1/2 at² = 1/2 × 8 × (10)² = 400m Reply

Answer:
400m
Explanation:
From Newton’s laws of motion,
s = ut + 1/2 at²
Here u = 0
s = 1/2 at²
= 1/2 × 8 × (10)²
= 400m
