Answer:
Time taken to accelerate to 48 m/s = 8 seconds
Explanation:
Initially the object is moving south at =
So, initial velocity of the object =
Acceleration caused by the force = 4
Final velocity towards south =
Using equation of motions:
where
final velocity
initial velocity
acceleration
time
Plugging in values.
Subtracting both sides by 16
Dividing both side by 4.
∴
Time taken to accelerate to 48 m/s = 8 seconds
Answer: 4m/s²
Explanation:
At stop signal car speed iz 0 ; V1=0m/s
After t=5s , car has speed is V2=20m/s
using:
a=(V2-V1)/t
a=(20m/s-0m/s)/5s
a=20m/s/5s
a=4m/s²
