Kinetic energy is mass times velocity square mv^2 (0.75*4^2=12)
Answer:
NO
Explanation:
Acceleration is change in velocityΔv in respect to timeΔt
so if the velocity of the car is greater than the truck it does not mean that the car acceleration is greater than the truck.
Sometimes with constant velocity it means no accelaration ,but the truck may have accelaration
so, higher velocity of the car does not mean higher acceleration
Explanation:
The newton (symbol: N) is the International System of Units (SI) derived unit of force.
no question please so what's the problem
Answer:
The final acceleration of the car, v = 70 m/s
Explanation:
Given,
The initial velocity of the car, u = 20 m/s
The acceleration of the car, a = 10 m/s²
The time period of travel, t = 5 s
Using the I equations of motion
v = u + at
= 20 + 10(5)
= 20 + 50
= 70 m/s
Hence, the final acceleration of the car, v = 70 m/s
