Question: Initially, the car travels along a straight road with a speed of 35 m/s. If the brakes are applied and the speed of the car is reduced to 13 m/s in 17 s, determine the constant deceleration of the car.
Answer:
1.29 m/s²
Explanation:
From the question,
a = (v-u)/t............................ Equation 1
Where a = deceleration of the car, v = final velocity of the car, u = initial velocity of the car, t = time.
Given: v = 13 m/s, u = 35 m/s, t = 17 s.
a = (13-35)/17
a = -22/17
a = -1.29 m/s²
Hence the deceleration of the car is 1.29 m/s²
Answer:
10 seconds
Explanation:
you multiply 100 by 10 in order to get 1000m
you add 200m to 1000m to get to the maximum of 1200m
since you travel at 100 per second, it took 10 seconds
False!
It’s false. The answer is False.
Answer:
If a material has high thermal conductivity, it is a conductor.
If a material has low thermal conductivity, it is an insulator.
