<span>Sharon
is jumping from an 18-foot diving board with an initial upward velocity
of 4 ft/s. When Susan jumps, Megan throws a beach ball up to Susan with
an initial upward velocity of 16 ft/s from a height 5 feet off the
ground. To the nearest hundredth of a second, it will take C. 1.08 seconds for the ball to reach Sharon after she jumps. </span>
Answer:21.45 m/s
Explanation:
Given
Mass of sport car=920 kg
Mass of SUV=2300 kg
distance to which both car skid is 2.4 m
coefficient of friction (
)=0.8
Let u be the initial velocity of both car at the starting of skidding
and they finally come to zero velocity
s=2.4 m
u=6.13 m/s
so before colliding sport car must be travelling at a speed of
(conserving momentum)
v=21.45 m/s
Answer:
telescope
