Answer:
40.47m/s²
Explanation:
Acceleration is the change in velocity of a body with respect to time.
Acceleration = change in velocity/time
Given speed = 1020km/hr
Time = 1.7s
Converting 1020km/hr to m/s we have;
(1020×1000/3600)m/s
= 1,020,000/3,600
= 283.3m/s
Acceleration = 283.3/7
Acceleration = 40.47m/s²
Deceleration is therefore 40.47m/s²
While a car is running, the alternator provides current to the battery and recharges it. Reduction reaction occurs at the anode of a lead-storage battery during this process .
The Lead-acid battery or lead-storage battery is one of the oldest types of rechargeable batteries.
Lead-storage batteries can be classified as secondary batteries. The chemical reactions that occur in secondary cells are reversible. The chemical process of extracting current from a secondary battery (forward reaction) is called discharging. The method of regenerating active material is called charging.
While recharging, the automobile battery functions like an electrolytic cell. The energy required to drive the recharging comes from an external source, such as an engine of a car. While charging reduction takes place at anode and while discharging oxidation takes place at anode.

Incomplete question as time is missing.I have assumed some times here.The complete question is here
Calculate the displacement and velocity at times of (a) 0.500 s, (b) 1.00 s, (c) 1.50 s, (d) 2.00 s, and (e) 2.50 s for a rock thrown straight down with an initial velocity of 10 m/s from the Verrazano Narrows Bridge in New York City. The roadway of this bridge is 70.0 m above the water.
Explanation:
Given data
Vi=10 m/s
S=70 m
(a) t₁=0.5 s
(b) t₂=1 s
(c) t₃=1.5 s
(d) t₄=2 s
(e) t₅=2.5 s
To find
Displacement S from t₁ to t₅
Velocity V from t₁ to t₅
Solution
According to kinematic equation of motion and given information conclude that v is given by
Also get the equation of displacement
These two formula are used to find velocity as well as displacement for time t₁ to t₅
For t₁=0.5 s
For t₂
For t₃
For t₄
For t₅
