Question

a car starts from rest and accelerates uniformly for 7s for a distance of 98 meters. find the acceleration​

Answer 1

Answer:

Your answer is 4m/s²

Explanation:

Given,

u = 0m/s

s = 98m

t = 7s

a = ?

Using the second equation of motion,

s = ut + 1/2 at²

98 = (0×7) + 1/2 × a × (7)²

98 = 0 + 1/2 × 49 × a

98 = 49/2 × a

98 ÷ 49/2 = a

98 × 2/49 = a

196/48 = a

4 = a

Therefore, the acceleration of the car is 4m/s²
