4 0

Answer:

Explanation:

1.)acceleration= final velocity-initial velocity/time

90m/s-0m/s /3seconds

=30m/s^2

2.) distance= speed*time

90m/s*3seconds

=270m

Which has greater mass of a bowling ball at rest for a rolling basketball which has greater momentum

IgorLugansk [536]

Answer:

The rolling basketball has greater momentum.

Explanation:

The momentum of an object is defined as the product of mass and velocity.

Given that the bowling mass has a greater mass than the basketball,

The bowling ball is at rest, so the velocity if the ball is zero.

The basketball is rolling, it has some velocity associated with it.

Therefore, the momentum of the bowling ball is zero.

The basketball has some momentum associated with it.

Hence, the rolling basketball has greater momentum.

A person wants to lose weight by "pumping iron". The person lifts an 80 kg weight 1 meter. How many times must this weight be li

statuscvo [17]

Answer:

37357 sec

or 622 min

or 10.4 hrs

Explanation:

GIVEN DATA:

Lifting weight 80 kg

1 cal = 4184 J

from information given in question we have

one lb fat consist of 3500 calories = 3500 x 4184 J

= 14.644 x 10^6 J

Energy burns in 1 lift = m g h

= 80 x 9.8 x 1 = 784 J

lifts required $= \frac{(14.644 x 10^6)}{784}$

= 18679

from the question,

1 lift in 2 sec.

so, total time = 18679 x 2 = 37357 sec

or 622 min

or 10.4 hrs
