We could determine the acceleration using this formula
Joe accelerated from 35 m/s to 50 m/s in 50 seconds, plug in the numbers
a=
a =
a =
a = 0.3
The acceleration is 0.3 m/s²
Enzymes can increase the rate of a reaction by lowering the activation energy needed for the reaction
Answer:
Acclⁿ = 18m/s² .
Explanation:
Mass = 10 kg
Frictional force is acting in opposite dirⁿ . Therefore the net force will be ,
=> F_net = 200N - Fricⁿ force
=> m * a_net = 200N - u mg
=> 10kg *a_net = 200N - 0.2*10*10
=> a_net = 180/10 m/s²
=> a_net = 18m/s²
