An object of mass 150 kg accelerates from a velocity of 5m/s to a velocity of 10m/s in the same direction. What is the impulse provided to cause this acceleration?

If it accelerated from 5 to 10 in one second then we know that acceleration is final (velocity-initial velocity)/

time

this gives (10-5)/1

=5m/s^2

force = mass x acceleration so = 150 x 5

this gives us a force of 750N

impulse is force x time so = 750 x 1

this tells us the impulse is 750 N.s

All of this is assuming it accelerated to 10m/s in one second.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
