padilas [110]2 years ago
5 0

Answer:

Acceleration = 3m/s^2

Vf= 0  Vi =35m/s   t= 13s

Explanation:

Acceleration = \frac{Change in velocity}{Change in time}\\                      = \frac{35m/s}{13s}\\             a       =   2.69m/s^2\\             a       =    2.7m/s^2\\    a   = 3m/s^2

What is the formula to find PE and KE ?
Lapatulllka [165]
PE stands for Potential Energy. It is the stored energy in an object due to its position with respect to some reference. It is expressed in Joules.

P.E = m * g * h    OR  P.E. = mgh

m - mass of the body
g - acceleration due to gravity
h - height attained due to the body's displacement.

K.E. stands for Kinetic Energy. It is the energy possessed by a body due to its motion.

K.E = 1/2 mv²    where m = mass of the body; v = velocity with which the body is moving.
