Answer:
v = 11 m/s
Explanation:
Given tha,
Initial speed, u = 5 m/s
Acceleration, a = 1.2 m/s²
Time, t = 5 s
We need to find the final speed of the boat during this time. Let it is v. Using first equation of motion as follows :
v = u +at
Putting all the values, we get :
v = 5 + 1.2(5)
v = 11 m/s
So, the final speed of the boat is 11 m/s. Hence, the correct option is (c).
1 gallon has 0.133681 cubic feet
Answer:
0.225 KJ kinetic energy is used for a person of mass 50 Kg running at speed of 3 m/s.
Explanation:
Given:
mass = 50 kg
velocity = v = 3 m/s
To Find :
Kinetic energy = ?
Solution:
Kinetic energy of an object is the energy that it possesses due to its motion.
The formula for kinetic energy is given as
But we required kinetic energy in KiloJoules i.e KJ
1 K = 1000 =
