Answer:
32.087 m/s
Explanation:
Velocity Initial = 5.6 m/s
time= 2.7
acceleration = 9.81
Velocity final = ?
Vf = Vi + at
Vf = (5.6) + (9.81)(2.7)
Vf = 32.087 m/s
Hello!
The balloon explodes, because the pressure builds up inside and the air want to expand. Letter a)
Hugs!
The force exerted by student A with his scooter is 306 N and that of student B is 204 N.
<h3>
Force applied by each student</h3>
The force exerted by each student is calculated from Newton's second law of motion.
F = ma
where;
- m is mass
- a is acceleration
F(A) = 127.5 x 2.4
F(A) = 306 N
F(B) = 120 x 1.7
F(B) = 204 N
Thus, the force exerted by student A with his scooter is 306 N and that of student B is 204 N.
