Calculate the velocity of a test sled that Is propelled by a device that has 2500 joules of available energy to propel a sled of 50 kg mass

A

10 m/sec

B

25 m/sec

C

50 m/sec

D

1 m/sec.

Text Solution

Verified by Experts

The correct Answer is:
C
`KE=(mv^2)/2` when KE=2500 joules , m=50 kg, and v=?
`2500=50/2(v^2)` i.e., 100=`v^2`
v=10 m/sec
