Explanation:
Given that,
Initial speed of the bus, u = 0
Acceleration of the bus, a = 0.5 m/s²
Let v is the velocity at the end of 2 minutes. The change in velocity divided by time equals acceleration.
So,
Let d is the distance cover during that time. So,
So, the final speed is 60 m/s and the distance covered during that time is 3600 m.

Answer: 258.7 J
Explanation:
Velocity of object V=5m/s
Mass ; 5kg
Height; h=4m
Mechanical energy is equal to sum of kinetic and potential energy
E=K+Ep
Kinetic energy is calculeted using; K=m*V²/2
Potential energy is calculated using : Ep=m*G*h
-------------------------------------------------------------------------
V=5m/s
m=5kg
h=4m
E=K+Ep
E=m*V²/2+m*G*h
E=5kg*(5m/s)²/2+5kg*9.81m/s²*4m
E=62.5J+196.2J
E=258.7 J
