Answer:
324.76J
Explanation:
Given parameters:
Force of pull on the box = 25N
Displacement = 15m
Angle of pull = 30°
Unknown:
Work done by the force = ?
Solution:
Work done is the force applied on a body to move it through a particular distance.
It can be expressed as;
Work done = F x dcosФ
F is the force
d is the displacement
Ф is the angle
So;
Work done = 25 x 15cos 30 = 324.76J

Answer:
The answer is B complimentary
Explanation:
Answer:
v = 36.05 m/s
Explanation:
It is given that,
Initial speed of the parachutist, u = 14.8 m/s
Altitude, h = 55.1 m
The acceleration due to gravity,
Let v is the speed of the shoe just before it hits the ground. The third equation of motion is given by :
v = 36.05 m/s
So, the speed of the show just before it hits the ground is 36.05 m/s. Hence, this is the required solution.
