Answer:
v = 15.23 m/s
Explanation:
Given that,
Mass of a car, m = 1110 kg
Initial velocity, u = 21 m/s
Force,F = -8000 N
Time, t = 0.9 s
We need to find the final velocity of the car.
Force, F = ma
So, the final velocity of the car is 15.23 m/s.

Hello there!
To find the speed when you have the kinetic energy and the mass, you just start with the kinetic energy formula then solve for speed.
Kinetic energy =
V =
V =
V = 0.02334
Thus, the speed is 0.02 m/s
I hope this helps!
Answer:
Explanation:
Given:
- mass of ice block,
- initial temperature of ice block,
- initial temperature of water,
- final temperature of mixture,
- specific heat of ice,
- specific heat of water,
- Latent heat of fusion of water,
<em>Now, assuming that there is no heat loss out of the mixture:</em>
⇒ heat absorbed by the ice = heat rejected by the water
