Answer:

125.5J

Explanation:

Given parameters:

Mass of the bowling ball = 6.1kg

Height of lifting = 2.1m

Unknown:

Increase in the ball energy = ?

Solution:

The ball has changed position by moving it from one point to another. So, it has acquired more potential energy.

Potential energy = mgh

m is the mass

g is the gravity

h is the height

Now insert the given parameters and solve;

Potential energy = 6.1 x 9.8 x 2.1 = 125.5J

Yuki888 [10]

Answer:

t = 7.76sec

Explanation:

t²=(2s)/a

t²=(2 x 50)/1.66

t²=60.24

t=√60.24

t=7.76sec

What is the normal force and gravitational force on a 55 kg person standing stationary?

Alex777 [14]

Answer:

539.55 N for both

Explanation:

F=ma

Mass is given at 55kg

And when finding gravitational force gravity's constant is an acceleration of 9.81m/s

F=(55)(9.81)

F= 539.55 N (for both)

Normal force cancels out gravitational force that's why we don't fall throught the floor.

We push down on the floor due to gravitational force but normal force keeps us upright pushing an equal amount back.
