Answer:
78
Explanation:
6318 78 = 81

81 = 81 to the nearest hundredth
81 = 81 to the nearest thousandth
= 0 to the nearest tenth
= 0 to the nearest hundredth

Acceleration of Car = 10 ms⁻²
Explanation:
Step 1:
The basic formula of acceleration is a = (v-u)/t ms⁻²
where, v- final velocity
u- initial velocity
t= time taken
Step 2:
Here v = 70 ms⁻¹
u = 50 ms⁻¹
t = 5 s
∴ a = ( 70 - 20)/5
a = 10 ms⁻²
