Answer:
The maximum height reached by the toy rocket is 0.73 meters.
Explanation:
It is given that,
Mass of the toy rocket, m = 0.8 kg
It is projected at an angle of 45 degrees from ground level. The kinetic energy of the rocket is used to find the velocity with which it was projected as :
u = 10.12 m/s
When it reaches to a maximum height, its final velocity will be equal to 0, v = 0
Using third equation of motion to find it as :
a = -g
s is the maximum height reached by the toy rocket
In vertical direction,
s = 0.36 meters
So, the maximum height reached by the toy rocket is 0.73 meters. Hence, this is the required solution.
Answer:
0.0044 J
Explanation:
The kinetic energy of an object is given by:
where
m is the mass of the object
v is the speed
For the ball in this problem,
m = 50.0 g = 0.050 kg
v = 42 cm/s = 0.42 m/s
Therefore, the kinetic energy is
