Answer:
25%
Explanation:
use F=mg
then use the answer you get from that and plug it into W=Fxh
take that answer and divide it by 400 J and multiply by 100

a) Work done = Net Kinetic Energy
= 1/2 x 50 kg x ((12m/s)^2 - (3m/s)^2)
= 0.5 x 50 Kg x (144 -9)(m/s)^2
= 3375 Kg (m/s)^2
b) Force = mxa
a = 120 N/50 Kg = 2.4 m/s^2
Using newtons third law of motion, we get-
V^2 - U^2 = 2 x a x S
S= (12^2-3^2)m^2/s^2/(2 x 2.4 m/s^2)
= 28.125 m
Answer:
796.2 m.
Explanation:
A sketch of the given question forms a right angled triangle with two given sides and a non included angle. Applying the appropriate trigonometric function, we have;
Tan θ = 
Let the horizontal distance required be represented by x, so that;
Tan 
= 
0.7536 =
⇒ x = 
= 796.1783
x = 796.2 m
Thus, the horizontal distance of the point of impact is 796.2 m.
So when the body moves in a straight line the average velocity is equal to the average speed. average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. this happens when a particle moves along a straight line in a fixed direction.
